Antonio Borneo 4622a95fcc helper/command: drop the TCL variable 'ocd_HOSTOS'
Commit 7a731eb637 ("Added HostOS variable"), merged in 2009,
adds a TCL global variable 'ocd_HostOS' that reports in a string
the OS of the host.
This was proposed as a workaround for jimtcl that didn't define
the standard TCL variable 'tcl_platform(os)'.

With commit 42f3fb7b7f46 ("Determine platform_tcl() settings with
configure"), merged in 2010 and part of jimtcl 0.70 issued in
early 2011, jimtcl provides the requires TCL standard variable
'tcl_platform(os)'.

The variable 'ocd_HostOS' has never been used by any TCL script
distributed with OpenOCD.

Drop the TCL variable 'ocd_HostOS'.

Antonio Borneo 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'.

Tarek BOCHKATI 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
	  protected areas: [0,4][7,9]

Antonio Borneo 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.

Marc Schink 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).

Tarek BOCHKATI 3d736e0488 flash/stm32l4x: STM32L55/L56xx basic support (non-secure mode)
STM32L5 have 512 Kbytes of Flash memory with dual bank architecture.
STM32L5 flash is quite similar to L4 flash, mainly register names
and offsets and some bits are changed.
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

  with external STLink-V3 or Nucleo-G474RE with two W25Q256FV in
  dual 4-line mode or STM32H73BI-Disco in octal mode
- tested with STM32L476G-disco (64MBit flash, 3-byte addr),
  STM32F412G-Disco, STM32F469I-Disco, STM32F746G-Disco, and

- suitable cfg for Discovery boards included
- limited parsing of SFDP data if flash device not hardcoded
  (tested only in single/quad mode as most devices either don't
  support SFDP at all or have empty(!) SFDP memory)
- 'set' command for auto detection override (e. g. for EEPROMs)
- 'cmd' command for arbitrary SPI commands (reconfiguration, testing etc.)
- makefile for creation of binary loader files
- tcl/board/stm32f469discovery.cfg superseded by stm32f469i-disco.cfg
- tcl/board/stm32f7discovery.cfg removed as name is ambiguous
  (superseded by stm32f746g-disco.cfg vs. stm32f769i-disco.cfg)
- dual 4-line mode tested on Nucleo-F767ZI, Nucleo-H743ZI and Nucleo-H7A3ZI-Q
  with two W25Q256FV, and on Nucleo-L496ZP-P and Nucleo-L4R5ZI
  with two W25Q128FV, sample cfg files included and on STM32H745I-Disco,
  STM32H747I-Disco, STM32H750B-Disco
- read/verify/erase_check uses indirect read mode to work around silicon bug in
  H7, L4+ and MP1 memory mapped mode (last bytes not readable, accessing last
  bytes causes debug interface to hang)
- octospi supported only in single/dual 1-line, 2-line, 4-line
  and single 8-line modes, (not in hyper flash mode)

Requirements:
GPIOs must be initialized appropriately, and SPI flash chip be configured
appropriately (1-line ..., QPI, 4-byte addresses ...). This is board/chip
specific, cf. included cfg files. The driver infers most parameters from
current setting in CR, CCR, ... registers.

Tarek BOCHKATI 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

Antonio Borneo 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.

Tim Newsome 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.
