89c6b93ba2 helper/command: fix memory leak on malloc() fail
If malloc() fails, the just allocated Jim_Obj will leaks.

Move Jim_IncrRefCount() before the malloc() and deallocate the Jim
object with Jim_DecrRefCount() on malloc() fail.

While there, add the 'out of memory' log and fix the CamelCase
name of the symbol tclOutput.

f18a801e03 helper/jim-nvp: remove unused function Jim_nvpInit()
The files jim-nvp.[ch] were originally inside jimtcl, then in 2011
they were dropped by jimtcl and integrated in OpenOCD.
The initial purpose was to make them as an independent library,
thus the presence of an 'init' function. Being now part of OpenOCD
do not require the 'init' function anymore, that is still empty
and unused, plus its name is in violation of the coding style.

Drop the function Jim_nvpInit().

3c73cca1e0 helper/types: remove type '_Bool'
Accordingly to OpenOCD coding style, both typedef and Camelcase

The type '_Bool' is not used in the code, having 'bool' as

Remove the definition of '_Bool' from 'types.h'.

11d918d9c1 libusb: don't use typedef's
Libusb defines both the struct and a typedef to the struct using
the same struct name. It's then possible to use either 'struct x'
and 'x'. E.g.:
	typedef struct libusb_device libusb_device;

OpenOCD is not consistent and uses a mix of 'struct x' and 'x'.

To make OpenOCD code uniform, stick at project's coding style and
use 'struct x' in place of the typedef'd name.

a60979b069 helper/command: fix build with jimtcl 0.79 or older
Commit a7d68878e4 ("helper/command: unregister commands through
their full-name") introduces for the first time in OpenOCD the use
of jimtcl API Jim_DeleteCommand().
The prototype of Jim_DeleteCommand() has changed with jimtcl 0.80
and the current code doesn't build with jimtcl 0.79 or older. This
is an issue for those distributions, like Debian, that provide
jimtcl as a separate package/library and have not switched yet to
the new jimtcl version.

Add a compile-time condition to cope with the jimtcl API change.

aacc26559e help: re-implement 'help' independent from tree of struct command
The current implementation of "help" related commands is tightly
connected to the tree of struct command.
The TCL commands 'add_usage_text' and 'add_help_text' have to add
fake commands in the tree of struct command to handle the help of
TCL procs.

Move all the help texts in a list accessible from the struct
command_context and register the commands through their full name.
Keep the list sorted alphabetically by the command name, so the
result of commands 'help' and 'usage' will be sorted too.

Remove the associated help and usage during commands un-register,
but call help_del_all_commands() for the text added through TCL
commands 'add_usage_text' and 'add_help_text'.

The resulting help and usage output is not changed by this patch
(tested on all the help and usage strings in current master
branch).

4289389937 helper/command: override target only on target prefixed cmds
In current code the current target is overridden whenever
jim_handler_data is not NULL. This happens not only with target
prefixed commands, but also with cti, dap and swo/tpiu prefixed
commands.
While this is not causing any run-time issue, by now, the
behaviour is tricky and makes the code cryptic.

Add a specific field to struct command for the target override so
the content of jim_handler_data can be restricted to command
specific data only (today only cti, dap and swo/tpiu).

Extend the API register_commands() to specify the presence of
either the command data or the override target.

The new API makes obsolete calling command_set_handler_data() to
set jim_handler_data, so remove it.

462323f123 helper/command: use one single handler for all the commands
Today openocd registers the commands to jim with three methods:
1) "native" commands (.jim_handler) at root level are registered
   directly as jim commands;
2) "simple" commands (.handler) at root level are registered
   through the handler script_command();
3) all other commands not at root level are registered through the
   handler command_unknown().

Apart from using different handler, other inconsistencies are
present:
a) command in 1) are not checked for their "mode", so are run with
   no check about current mode (COMMAND_CONFIG or COMMAND_EXEC);
b) target_call_timer_callbacks_now() is called only for "simple"
   commands and not for "native" commands;
c) target override is performed only for "simple" commands and not
   for "native" commands.

Drop script_command() and extend command_unknown() to uniformly
handle all the cases above, fixing all the inconsistencies already
mentioned.
The handler's name command_unknown() is probably not anymore
appropriate, but will be renamed in a separate change.

Note: today all the commands in a) have mode CONFIG_ANY, apart for
"mem2array" and "array2mem" that have mode COMMAND_EXEC. But the
latter commands are registered during target init, so do not exist
during COMMAND_CONFIG and no issue is present.

a510c8e23c helper/command: always pass struct command as jim private data
While registering a new command, jim accepts a pointer to command's
private data that will be accessible during the command execution.

Today openocd is not consistent and passes different private data
depending on the command, and then even overwrites it:
- "simple" commands (.handler) are registered with their own
  struct command pointer as command private data;
- "native" commands (.jim_handler) at root level are registered
  with NULL command private data;
- "native" commands (.jim_handler) not at root level are
  registered with the struct command pointer of their root command
  as command private data but, when executed, the command private
  data is overwritten by the value in field jim_handler_data taken
  from their struct command.

Uniform the usage of command private data by always set it to the
struct command pointer while registering the new commands.
Note: for multi-word commands only the root command is registered,
so command private data will be set to the struct command of the
root command. This will change later in this series when the full-
name of the command will be registered.

Don't overwrite the command private data, but let the commands that
needs jim_handler_data to get it directly through struct command.

For sake of uniformity, let function command_set_handler_data() to
set the field jim_handler_data also for "group" commands, even if
such value will not be used.

Now Jim_CmdPrivData() always returns a struct command pointer, so
wrap it in the inline function jim_to_command() to gain compile
time check on the returned type.
While there, uniform the code to use the macro Jim_CmdPrivData()
to access the command's private data pointer.

0f06d94336 mem_ap: allow GDB connections
The target mem_ap is a convenient way to access buses, memory and
peripherals behind an ARM AP.
The current implementation provides only access through OpenOCD
commands, because GDB remote protocol has to interact with a CPU
and has to operate on CPU states and registers.
Using GDB to access the memory is welcome, because GDB can resolve
the symbol's address from an ELF file and can nicely display the
content of complex struct and data types.

Extend mem_ap target with the bare minimal support for a remote
GDB connection, by emulating a fake basic ARM core. It means that
only a GDB that has support for ARM can be used (either 'aarch64',
'arm' or 'multiarch' GDB). This is not seen as a big limitation,
because the mem_ap target is mainly used on ARM based devices.

Add a minimalist register description for the fake CPU.
Fill the field 'debug_reason' as expected by GDB server.
Call the target halted event to reply to GDB halt requests.

For backward compatibility, don't open the GDB port by default. If
needed, it has to be specified at 'target create' or 'configure'
with the flag '-gdb-port'.

There are some breakpoint/watchpoint related code in armv8_dpm.c,

same logic to add watchpoint support for target aarch64.

This commit also increases the size of stop_reason[] in function
gdb_signal_reply() since the old size is too small to fit in a
64-bit address, such as ffff8000115e6980.

01030fb893 drivers/cmsis-dap: tidy up buffer access
Each one of CMSIS-DAP command handlers was responsible for setting
HID report number, which in case of USB bulk transport was not used
at all. The command had to be filled with 1 byte offset whereas
the response was read without an offset.

Introduce 'command' and 'response' pointers into struct cmsis_dap.
Use them for filling the command and read the response respectively.
CMSIS-DAP command parameter are now at positions as documented in
https://arm-software.github.io/CMSIS_5/DAP/html/group__DAP__Commands__gr.html
Adjust buffer allocation for HID and USB bulk transports.

While on it, use h_u32_to_le() and h_u16_to_le() instead of per-byte
writes.

fed42ccfd3 cmsis-dap: don't update the packet size across backends.
The hidapi cmsis-dap backend is using a packet_size of
64+1: 64 is the bMaxPacketSize0 and 1 is the hid Report-Id.

In hidapi::hid_write(), the packet_size is decremented by 1 and
stored for the next transfer.
The packet_size is now valid bMaxPacketSize0=64,
so when hid_read() is called, libusb_bulk_transfer() finishes w/o timeout.

For the libusb bulk backend, the same packet_size of 64+1 is used,
but there's no hid_write() to decrement and store it for the next read.

So the next time a read is done, it will try to read 64+1 bytes.

Fix this by putting the packet logic within each backend.
Use calloc() to allocate the struct cmsis_dap to be on safer side.

36ae487ed0 jimtcl: add temporary workaround for memory leak in jimtcl 0.80
The API Jim_CreateCommand() in latest version of jimtcl leaks the
memory allocated internally by jimtcl when it converts the string
command-name to a Jim_Obj.
The fix is already merged upstream and would be available in next
jimtcl 0.81, expected in ~6 months, hopefully before the next tag
for OpenOCD v0.12.0.
OpenOCD v0.11.0 is distributed with jimtcl 0.79.
Debian distributes jimtcl as a separate library package and today
it's still on 0.79.

It make sense to keep using jimtcl 0.80 in current development
cycle to test it further. But having this background memory leak
noise hides the eventual new memory leaks that could come from the
development activity.

This patch uses the internal jimtcl API Jim_CreateCommandObj() and
correctly free the internal object, avoiding the memory leak.
Being an internal API, it is not accessible if OpenOCD is linked
with an external jimtcl library. Nevertheless, building jimtcl as
a submodule of OpenOCD makes the trick effective.

The scope of this patch is thus limited at developers that build
OpenOCD with jimtcl submodule and need to control and debug memory
leaks.
This patch is supposed to be removed as soon as jimtcl 0.81 gets
available.

The added code is located, on purpose, in an area of the file that
hopefully will not conflict other patches pending in gerrit.

03e2bc0f3b flash/stm32l4x: enhance protect handler to use efficiently all WRP areas
stm32l4_protect: was using one WRP area per bank, without checking
if it is already protecting some sectors.
protection algo is more complicated than that, before using a WRP area
we should check if it is already used, then either reuse it for extension
(or reduction) or use a free area.

introduce a new command: stm32l4x wrp_info bank_num ['bank1'|'bank2']
this command lists the protected areas using WRP.

Note: for some devices like STM32L4R/S in single bank mode, all 4 WRP areas
are usable for that bank, to manage this case an attribute 'use_all_wrpxx'
was introduced into stm32l4_part_info and used later in protection handlers

example usage:
	$ telnet localhost 4444
	> flash probe 0
	  device idcode = 0x10036470 (STM32L4R/L4Sxx - Rev: Y)
	  flash size = 2048kbytes
	  flash mode : dual-bank
	  flash 'stm32l4x' found at 0x08000000
	> stm32l4x wrp_info 0
	  no protected areas
	> flash protect 0 0 4 on
	  set protection for sectors 0 through 4 on flash bank 0
	> flash protect 0 8 9 on
	  set protection for sectors 8 through 9 on flash bank 0
	> stm32l4x wrp_info 0
	  protected areas: [0,4][8,9]
	> flash protect 0 6 6 on
	  the device WRPxy are not enough to set the requested protection
	  failed setting protection for blocks 6 to 6
	> flash protect 0 3 5 on
	  set protection for sectors 3 through 5 on flash bank 0
	> stm32l4x wrp_info 0
	  protected areas: [0,5][8,9]
	> flash protect 0 6 7 on
	  set protection for sectors 6 through 7 on flash bank 0
	> stm32l4x wrp_info 0
	  protected areas: [0,9]
	> flash protect 0 5 6 off
	  cleared protection for sectors 5 through 6 on flash bank 0
	> stm32l4x wrp_info 0

With zy1000 removed, there is no other implementation that uses

While the idea of the minidriver is probably still valid (that is
to intercept jtag primitives before serialization), there is no
current use case, no guarantee it is really working, and the way
it was implemented (by macros and #if conditionals) is really hard
to maintain and test.

Let's let it rip in git history, from where it could eventually be
taken back in a more modern implementation.
The entry points of minidriver API are still in the code with the

faaa42283f stlink: fix execution order in stlink_config_trace()
The change [1] guarantees that the value pointed by 'prescaler'
gets always set, even when the adapter does not support the
specific mode requested (e.g. sync), or during trace disabling.
This works fine with the code in armv7m_trace_tpiu_config(), but
requires all the parameters to be valid also to disable the trace
(with 'enable==false'), otherwise returns error on incorrect
parameters or even causes segmentation fault if pointers
'trace_freq' or 'prescaler' are NULL.

Another problem in stlink_config_trace(), not linked with [1], is
caused by a tentative to change the settings on an already enabled
trace; the trace is disabled before the new parameters are fully
validated and in case of invalid parameters the trace is not
re-enabled.
It would be more logical to first check all the parameters, then
disable the trace, change the settings and re-enable the trace.

Practically revert [1] by checking 'enable==false' at function
entry, then disable trace and exit without any further check on
the other parameters.
For the case 'enable==true', validate all the function parameters
then disable the trace, update the trace settings and re-enable
the trace.
Modify the caller armv7m_trace_tpiu_config() to initialize the
variable 'prescaler' to a safe value to avoid the issue targeted
by [1].

Note: ST-Link TCP server does not support the SWIM transport.

ST-LINK TCP server allows several applications to connect to the same
ST-Link through sockets (TCP).

To use ST-LINK TCP server:
 - using stlink-dap : use 'st-link backend tcp [port]'
 - using hla : use 'hla_stlink_backend tcp [port]'

the default port value is 7184

23d8831391 target: avoid polling during 'resumed' event handler
OpenOCD is based on a single main loop that schedules all the
activities.
At the execution of a TCL command, the timestamp is checked to
eventually trigger the polling of the targets. This means that by
executing a TCL command the polling can be triggered and detect a
change of target's state.

When openocd 'resumes' a target, the target can halt again by
hitting a breakpoint.
The 'resumed' event handler is started just after the target has
been resumed, but it triggers a polling before the execution of
its very first instruction.
If the polling finds the target halted, it will run the 'halted'
event handler, that will then be executed 'before' the pending
'resumed' handler.

In case of gdb, a 'continue' command will restart the target but,
polling (and halt detection) executed before the end of the resume
process will hide the halt. As a consequence, the gdb will not be
informed of the halt and will remains waiting as if the target is
still running without showing the prompt.

This can be verified by running on the target a firmware with a
loop, run openocd with a dummy 'resumed' event, and let gdb to set
a breakpoint in the loop. A 'continue' command will cause the
target to halt again by hitting the breakpoint at the next loop
iteration, but gdb will loose it and will not return the prompt.

	openocd -f board/st_nucleo_f4.cfg -c \
		'stm32f4x.cpu configure -event resumed {echo hello}'
	arm-none-eabi-gdb -ex 'target remote :3333' -ex 'b *$pc' -ex c

Disable the polling while executing target's resume().
Document it and provide hints to developers to cope with future
implementation.

090209275b jlink: fix device discovery when network is off
If user specifies a serial number for the jlink device, openocd
extends the search to network jlink devices too, without checking
if the host has a valid and functional network connection. If the
network is not functional, libjaylink returns error. This error
invalidates the discovery on USB, even if it was successful.

Factor-out parts of the jlink_init into separate jlink_open_device
function, use that function to firstly discover and match USB
devices and, if matching device was not found on the USB bus and
serial number was specified, repeat discovery and matching via TCP.

Fixes: https://sourceforge.net/p/openocd/tickets/294/

bd1adcffe7 configure: drop macro 'AC_HEADER_TIME'
The macro AC_HEADER_TIME has been obsoleted by autoconf 2.70.

Not all systems provide 'sys/time.h', plus some old system didn't
allowed to include both 'time.h' and 'sys/time.h' because 'time.h'
was included by 'sys/time.h' and was not properly protected to
allow multiple inclusion.
The macro AC_HEADER_TIME helps to detect such odd case.
Nowadays all the systems properly protect 'time.h', so its safe to
unconditionally include 'time.h', even if it is also included by
'sys/time.h'.

The case of systems without 'sys/time.h' is already covered by
configure.ac through the directive
	AC_CHECK_HEADERS([sys/time.h])

Remove the obsoleted autoconf macro and simplify the code by
including 'time.h' unconditionally and check HAVE_SYS_TIME_H to
include 'sys/time.h'.

0b248e04c1 driver/ftdi: skip trst in swd mode
When using the adapter olimex arm-jtag-swd (to convert to SWD a
JTAG-only FTDI adapter), the pin trst on JTAG side is re-used to
control the direction of pin SWDIO on SWD side.
There is a single reset API at adapter driver to assert/deassert
either srst and/or trst. A request to assert/deassert srst can
cause also trst to change value, hanging the SWD communication.

In SWD mode, ignore the value passed to trst.

http://openocd.zylin.com/3641/

While all of these mismatches should hopefully be cleaned by the

second patch is required for dapdirect transports, either
dapdirect_swd and dapdirect_jtag.

Extend the existing workaround to all non-jtag transports.

a56b729191 arm7_9_common: fix host endianness bug in arm7_9_full_context()
The original code passes to ->read_core_regs() and to
->read_xpsr() the pointer to the little-endian buffer reg.value.
This is incorrect because the two functions above require a
pointer to uint32_t, since they already run the conversion with
arm_le_to_h_u32() in the jtag callback.
This causes a mismatch on big-endian host and the registers get
read with the incorrect endianness.

Use an intermediate buffer to read the registers as uint32_t and
to track the destination reg.value pointer, then copy the value in
reg.value after the call to jtag_execute_queue().

Tested with qemu-armeb and an OpenOCD built through buildroot
configured for cortex-a7 big-endian.

Note that if jtag_execute_queue() fails, the openocd register
cache is not updated, so the already modified flags 'valid' and
'dirty' are incorrect. This part should be moved after the call to
jtag_execute_queue() too.

7b641d3d4e Add initial RTT support
Real Time Transfer (RTT) is an interface specified by SEGGER based on
basic memory reads and writes to transfer data bidirectionally between
target and host.
Every target that supports so called "background memory access", which
means that the target memory can be accessed by the debugger while the
target is running, can be used.

RTT is especially of interest for targets which do not support Serial
Wire Output (SWO) (e.g. ARM Cortex-M0) or where using semihosting is
not possible (e.g. real-time applications) [1].

The data transfer is organized in channels where each channel consists
of an up- and/or down-channel. See [2] for more details.

Channels are exposed via TCP connections. One or more RTT server can be
assigned to each channel to make them accessible to an unlimited number
of TCP connections.

The current implementation does not respect buffer flags which are used
to determine what happens when writing to a full buffer.

Note that the implementation is designed in a way that the RTT
operations can be directly performed by an adapter (e.g. J-Link).

646c3c9902 arm_adi_v5: prevent possibly endless recursion in dap_dp_init()
If dap_dp_read_atomic() in 30 trials loop fails, dap->do_reconnect is set.
Following dap_dp_read_atomic() calls dap_queue_dp_read() which in case
of SWD transport calls swd_queue_dp_read(). It starts
with swd_check_reconnect() and it calls swd_connect() because
dap->do_reconnect is set. swd_connect() does some initialization,
reads DPIDR and calls dap_dp_init() again!

Moreover if dap_dp_init() is called from cortex_m_reset_(de)assert()
one level of recursion is necessary to reconnect the target.

Introduce dap_dp_init_or_reconnect() for use in cortex_m reset

a03ac1ba30 helper/command: disable logging of registered commands [RFC]
Every debug log of OpenOCD contains approximately 130 lines like:

Debug: 264 147 command.c:354 register_command_handler(): registering 'flash'...

Because only root name of the command is logged, most of lines is not
too informative. E.g. registering 'flash' is repeated 14 times.

Karl Passon submitted the patch [1] changing the logged cmd name from
root to lowest level. It makes the log better. Unfortunately we also have
'reset_config' and 'cortex_m reset_config' and similar which looks
equal in the log after [1].
Moreover [1] has not been reviewed for 5 years.

So my guess is that nobody uses that crap in debug log.

Save more than 10 kbytes in any debug log and make log analyse easier
by blocking log command in #if 0 block.
If some developer eventually needs to debug cmd registering he can easily
enable logging again.

STM32L5 have 512 Kbytes of Flash memory with dual bank architecture.
STM32L5 flash is quite similar to L4 flash, mainly register names

NON-SECURE flash is located at 0x8000000 like L4 devices, so no
big change is needed (secure flash will be subject of another change).

Note: flash driver name is set stm32l5x, in order to extend the commands
with specific L5 commands (to manage TZEN for example ...)

Note: this works only when TZEN=0

dc43ecce5a flash/stm32l4x: introduce table with register offsets
This change is a preparation for STM32L5 support on top of L4 driver
STM32L5 flash is quite similar to L4 flash, mainly register names
and offsets and some bits are changed.

flash_regs table is introduced within stm32l4_flash_bank struct in order
to get correct register offsets, by using the driver internal function
'stm32l4_get_flash_reg_by_index'.

To use efficiently register indexes, stm32l4 _[get|read|write]_flash_reg
functions are surcharged to accept register indexes.

IMPORTANT: stm32l4_write_option is not surcharged, and they always accept
the option register offset.

tested on NUCLEO-G474RE and STM32L4R9I-DISCO

- attempts connection to any device with user class and 2 bulk endpoints
- regardless of cmsis_dap_vid_pid or cmsis_dap_serial setting

Distinguish between real match and no filtering cases and use that info
appropriately.

Add debug messages to show why the interface is refused.

Move CMSIS-DAP interface string detection before checking of class/endpoints
to give more understandable debug log in the case the device is refused.

Keep track of reliable matches in both device and interface enumeration.
First search for the interface with CMSIS-DAP in the interface string.
If it fails, chose the first suitable interface.

608299484d flash/nor/psoc6: remove setting of xPSR.T bit from sromalgo_prepare()
PSoC6 erases flash to 0x00 not more common 0xff, so a device
with erased flash loads xPSR.T=0 from the zeroed reset vector.
Wrong thumb bit value caused a target algorithm failed with HardFault.
The low level write to xPSR solved the problem only if xPSR cached
copy was not marked dirty.

Later commit 49bd64347a fixed T setting
for all Cortex-M target algorithms.

Since 49bd64 this part of code is useless as xPSR target_start_algorithm()
sets always xPSR dirty so the effect of the low level write is eliminated
(and proper setting of thumb bit is ensured in target_start_algorithm())

f32ca2d25d target/cortex_m: remove wrong xPSR.ICI/IT bits handling
If a Cortex-M (not M0, M0+) target was stopped in the middle of
a conditional IT block or in the load/store multiple instruction,
cortex_m_debug_entry() used wrong xPSR bits to detect it and then
cleared 8 bits of the exception number from xPSR
- probably wrong bit mask again.

I believe clearing of the ICI/IT bits in cortex_m_debug_entry() has no
reason as Cortex-M does not use instruction injecting.

Remove the wrong code.

Add a comment in the API definition to highlight this, in case it
get used by a further hla implementation, then rename as 'regsel'
the 'num' parameter.

specific, cf. included cfg files. The driver infers most parameters from
current setting in CR, CCR, ... registers.

and on minidriver-dummy build. The check on BUILD_ZY1000 was added
to pass the auto-build in jenkins. While the build issue with
minidriver-dummy was known, as reported in the comment, it was not
addressed and got ignored for slightly more than one year.

Use the macro HAVE_JTAG_MINIDRIVER_H in place of BUILD_ZY1000 to
take in account both builds that require the minidriver.
Fix also the build in case configure enables the HLA drivers due
to autodetection of libusb. The HLA drivers would not be in the
build and the function transport_is_hla() would be missing.

9cce6b3c76 armv7m: add a TCP channel to stream captured trace
When trace capturing the trace is enabled using 'tpiu_config internal'
(via the internal mode), OpenOCD can collect the trace buffers then append
it to a specified file or named pipe and propagate the trace to 'tcl_trace'
command.
This change is allowing OpenOCD to stream the captured trace over TCP.

When using this configuration OpenOCD acts like a server and multiple
clients can connect and receive the captured trace.

Example on STM32F7 running at 216MHz:
  itm port 0 on
  tpiu config internal :3344 uart off 216000000

7e6556b3ca server: permit the add_service function to return the created service
returning the created service seems useful:

as the only method to get the freshly created service is by getting the
last item in the services linked list, and this seems to be like an
intrusion to service internal mechanism.

possibly, we could get the service from a connection but this is possible
only from [new_connection|input|connection_closed]_handler_t, but this is
not always practical:
  example: armv7m: add a TCP channel to stream captured trace
           http://openocd.zylin.com/#/c/5345/
           here we poll for trace and broadcast to all connections
           outside of these xxx_handler_t functions

also, storing one of the connections in new_connection_handler_t and get
the service from it is possible, but this will make the code less readable.

72a1010c9f openocd: convert function setup_command_handler() to static
The function setup_command_handler() was used in the eCos build of
OpenOCD, thus it was exported and a comment was added to remark it
should remain not-static. Unfortunately the comment was missing
the relevant information of the special build that requires so.
Also unusual is that there is no include file that declares the
prototype of the function.

The comment above the function was added in two steps, in commit
ea3e49f4e2 ("fix embedded builds") and commit fb96b8607a
("openocd: setup_command_handler() must not be static"), again
without info about the special build.
Also the mailing list archive does not report any further detail.
The only hint is in the first commit above that also adds a test
on BUILD_ECOSBOARD in a #if.

Commit 39650e2273 ("ecosboard: delete bit-rotted eCos code")
removes all the eCos code, that effectively includes the both the
prototype and the call to the function setup_command_handler(),
	http://openocd.zylin.com/#/c/503/2/src/ecosboard.c@a1092
but did not reverted the function to static.

With all the 'external' uses of this function being dropped, set
the function setup_command_handler() to static and remove the
obsoleted and misleading comment.

e2e8a5f467 gdb_server: allow multiple GDB connections to selected targets
The default way of working is to have a single GDB attached to one
target, so OpenOCD accepts only one connection to the GDB port of
each targets and rejects any further connection.

There are some barely safe use cases in which it could get useful
having a second GDB connection to the same target.
One such use case is while using GDB as a 'non-intrusive memory
inspector', as explained in the OpenOCD documentation.
One GDB can be left running an infinite loop to dump some memory
area, or even analysing the content, while keeping a second GDB
ready for user interaction or spot memory check.

Add a target configure option to specify the maximum number of GDB
connections allowed for that target, keeping the default to 1.

d3aa2d3536 target/cortex_m: reduce duplication in profiling
The Cortex-M implementation of profiling contains a bunch of
conditionals and checks to handle both chips which have PCSR and chips
which do not. However, the net effect of the non-PCSR branches is
actually exactly the same as what target_profiling_default does. Rather
than duplicating this code, just detect the situation where PCSR isn’t
available and delegate to target_profiling_default.

a7502ee8b9 target: allow profiling from running
There are a handful of implementations of profiling. There is the
default implementation, which repeatedly halts and resumes the target,
sampling PC each time. There is the Cortex-M implementation, which
uses PCSR if available, otherwise falling back to halting and resuming
and sampling PC. There is the OR1K implementation, which reads NPC
repeatedly. Finally, there is the NDS32 implementation which uses some
kind of AICE commands with which I am unfamiliar.

None of these (with the possible exception of the NDS32
implementation) actually require the target to be halted when starting
profiling. The Cortex-M and OR1K actually resume the target as pretty
much their first action. The default implementation doesn’t do this,
but is written in such a way that the target just flips back and forth
between halted and running, and the code will do the right thing from
either initial state. The NDS32 implementation I don’t know about.

As such, for everything except NDS32, it is not really necessary that
the target be halted to start profiling. For the non-PCSR Cortex-M and
default implementations, there is no real harm in such a requirement,
because profiling is intrusive anyway, but there is no benefit. For
the PCSR-based Cortex-M and the OR1K, requiring that the target is
halted is annoying because it makes profiling more intrusive.

Remove the must-be-halted check from the target_profiling function.
Add it to the NDS32 implementation because I am not sure if that will
break when invoked with a running target. Do not add it to any of the
other implementations because they don’t need it.

491636c8b8 flash/nor/nrf5: check protection before flash erase/write on nRF51
nRF51 devices have a clumsy flash protection based on UICR CLENR0.
A code running in RAM can write to a protected flash region without
any hint the protection gets violated.
NVMC flash page erase obeys protection setting but fails absolutely
silently.

Before this change the first problem was not addressed in the code.
To justify the second one, protection was loaded during probe,
after protection setting and after a mass erase.

Move protection updates to the beginning of erase/write operation
and limit them to nRF51 series only. Check for protected sectors
before write.

The change also fixes the problem of 'nrf5 mass_erase' on
nRF52833/840 devices. They use ACL flash protection, which is not
supported in nrf5 driver. mass_erase then looked like it failed.

c97ccc8971 flash/nor/nrf5: fix protection setting on nRF51
Protection setting has not ever worked. UICR CLENR0 register cannot
be simply written but has to programmed because it resides in UICR
page of the flash.

Enable flash programming before writing CLENR0 and set back to r/o
afterwards.

Inform the user that reset might be required.

b68674a1da Upstream tons of RISC-V changes.
These are all the changes from https://github.com/riscv/riscv-openocd
(approximately 91dc0c0c) made just to src/target/riscv/*. Some of the
new code is disabled because it requires some other target-independent
changes which I didn't want to include here.

Built like this, OpenOCD passes:
* All single-RV32 tests against spike.
* All single-RV64 tests against spike.
* Enough HiFive1 tests. (I suspect the failures are due to the test
suite rotting.)
* Many dual-RV32 (-rtos hwthread) against spike.
* Many dual-RV64 (-rtos hwthread) against spike.

I suspect this is an overall improvement compared to what's in mainline
right now, and it gets me a lot closer to getting all the riscv-openocd
work upstreamed.

3ffa14b043 target/aarch64: fix use of 'target->private_config'
The function adiv5_jim_configure() casts the void pointer
'target->private_config' to a struct adiv5_private_config pointer.
This is tricky in case of aarch64, where the private data are in a
struct aarch64_private_config that has as first element the struct
adiv5_private_config.

While the current solution is working fine, it's not clean and
requires special attention for any further code development.

Override 'target->private_config' to the correct pointer while
calling adiv5_jim_configure().

4dade98c44 FreeRTOS: properly read on big endian systems.
Remember, don't cast your pointers between types of different sizes!

While the FreeRTOS handlers attempt to account for different pointer and
list widths, the types used are always fixed, so this will _remain_
broken if/when someone targets FreeRTOS on 8/16/64 bit targets. (Note
that this patch does not _change_ that, it was fixed to 32bit before as
well)

In the meantime, this properly handles 32bit reads on a mips BE system
(ath79) as well as remaining fully functional on x86_64.

051e80812b drivers/jlink: fix calculate_swo_prescaler formula
a) TPIU_ACPR is defined as:
	SWO_baudrate = TRACECLKIN/(TPIU_ACPR +1)

b) TPIU_ACPR is set by armv7m_trace_tpiu_config()
	target_write_u32(target, TPIU_ACPR, Prescaler-1), so
	TPIU_ACPR = Prescaler-1

Replacing TPIU_ACPR in a), we get:
	SWO_baudrate = TRACECLKIN/Prescaler, so

c)	Prescaler = TRACECLKIN/SWO_baudrate

The Prescaler calculated by calculate_swo_prescaler() is greater by 1:
	Prescaler = TRACECLKIN/SWO_baudrate + 1

The second problem is that even in situations when
an exact baudrate match is possible,
the resulting TRACECLKIN/Prescaler already has a 3% deviation.

For example, TRACECLKIN=88000000, SWO_baudrate=500000,
calculate_swo_prescaler will return Prescaler=171.
The correct value should be Prescaler=176 (TPIU_ACPR=175).

d493b53e8c jtag/aice: avoid abusing of int32_t type
In several cases the 'int' status value returned by libusb and by
aice internal functions is taken in a variable of type 'int32_t',
requiring an implicit (but trivial) cast.
This makes compulsory using 'PRId32' in the format strings that
print such 'int32_t' result and requires an additional implicit
conversion to return the 'int32_t' as 'int'.

Replace to type 'int' all the occurrences of 'int32_t result' and
fix accordingly the format strings.

Plus, all the size of aice commands are stored as int32_t const
variables with uppercase name, violating the coding style, and are
then passed as 'int' parameter to the read/write functions.

Replace the variables with C macros carrying an 'int' value.

While there, replace also a 'uint32_t' loop index with 'unsigned'
and fix the format string in the loop.

4e98d44fd1 openocd: avoid checking for non NULL pointer to free it
The function free() can be called with a NULL pointer as argument,
no need to check the argument before. If the pointer is NULL, no
operation is performed by free().

Remove the occurrences of pattern:
	if (ptr)
		free(ptr);

While there replace a sequence malloc(size)+memset(,0,size) with a
calloc(1,size).
Replace a pointer assignment to '0' with an assignment to NULL.
In server/*, an error is logged if the ptr was already NULL. This
cannot happen since the pointer was already referenced few lines
before and openocd would have been already SIGSEGV in that case,
so remove the log.

There are cases where the pointer is set to NULL after free(), but

this is evident. Anyway, the compiler will remove the useless
assignment so no reason to be too much aggressive in this change.

1457a1ab42 tcl/target: use command 'jtag newtap' to add a boundary scan TAP
A JTAG TAP for boundary scan should be added in the scan chain
through the command "jtag newtap".
In some TCL target script the boundary scan TAP is added through
the command "swj_newdap", command that is inappropriate in this
context because specific for arm adi-v5 SWJ-DP.
This situation was probably created to bypass the error with HLA
framework, caused by missing command "jtag newtap".

Add the command "jtag newtap" in HLA, by reusing the existing
code for command "hla newtap".
Fix the TCL target scripts to use the command "jtag newtap" for
the boundary scan TAPs.

The TCL script target/psoc6.cfg has no evident reference to HLA,
so the reason for using "swj_newdap" is less clear. Nevertheless
it uses the wrong command and, once HLA is fixed, there is no
reason to avoid fixing it too.

thus called even before main().
With debug_level set to LOG_LVL_USER=-1 all the LOG_ERROR() get
dropped.
Properly initializing debug_level cause segmentation fault due to
log_output still not initialized.

Initialize debug_level to LOG_LVL_INFO so errors get printed.
Handle separately the case of log_output still NULL, meaning that
log_init() is not called yet.

2f92598f0d gdb_server: refuse gdb connection if target is not examined

Plus, since OpenOCD does not implements non-stop mode yet, gdb
expects the target to be halted by the inferior when the
connection is established.
Print a warning to inform the user in case the target is not
halted, but still accept the gdb connection to permit the

768502403e target: use one second timeout while halting target at gdb attach
By default GDB timeouts after 2 seconds, even if this value can be
modified with GDB command "set remotetimeout".
On OpenOCD side, the default event for GDB attach is to halt the
target and wait it to halt. But here the default timeout of the
halt command is 5 seconds!
If the target cannot be halted (e.g. it's kept in reset by another
core or the debugger doesn't have enough privileges) then GDB will
timeout while OpenOCD is still waiting and is unable to
communicate with GDB.

Decrease the halt timeout to 1 second in the default GDB attach
event handler.

19aa77cc7f target/arm7tdmi: fix memory leak of register cache
There is no method to free the register cache, allocated in
arm7tdmi_init_target(), so we get a memory leak.
Issue identified by tracking all calls to arm_build_reg_cache().

Implement the method arm7tdmi_deinit_target() that in turn calls
arm7tdmi_free_reg_cache().

NOT TESTED on a real arm7tdmi target.
Tested on a arm926ejs (SPEAr320) by hacking the target type and
pretending it is a arm7tdmi:
	sed -i s/arm926ejs/arm7tdmi/ tcl/target/spear3xx.cfg

df1dcc27ee target/xscale: fix memory leak of register cache
There is no method to free the register cache, allocated in
xscale_build_reg_cache(), so we get a memory leak.
Issue identified by tracking all calls to arm_build_reg_cache().

Implement the method xscale_deinit_target() that in turn calls the
new xscale_free_reg_cache().
Fix leak of struct xscale.

NOT TESTED on a real xscale target.
Tested on a arm926ejs (SPEAr320) by hacking the target type and
pretending it is a xscale:
	sed -i s/arm926ejs/xscale/ tcl/target/spear3xx.cfg

580b8f5da0 target: fix memory leaks on targets based on arm9tdmi
Similarly to the fix for arm926ejs (also base on arm9tdmi), fix
the other targets based on arm9tdmi.
The fix for arm926ejs is tested on SPEAr320 target.

This fix is proposed separately because is not tested on a correct
target device, but tested on SPEAr320 by hacking the target type
and pretending it is the correct one, e.g.:
	sed -i s/arm926ejs/arm920t/ tcl/target/spear3xx.cfg

The memory leaks detected and fixed are:
- arm register cache;
- EmbeddedICE register cache;
- arm_jtag_reset_callback internal data;
- struct <target_type>_common.
