Tim Newsome db16b3dc5b Call poll at a fixed interval.
The existing implementation blocks in select() for a fixed amount of
time. This change tracks when the next event (likely poll()) wants to be
run, and uses a shorter timeout in select() if necessary.

Also track all these timeouts using milliseconds as returned by
timeval_ms() instead of `struct timeval` to simplify the code.

This feature is helpful if poll() wants to do something like sample PCs
or memory values for basically the entire time that otherwise OpenOCD
would be hung in select(). See
https://github.com/riscv/riscv-openocd/pull/541 for an example of that.
The RISC-V code using this change will be upstreamed some day, too.

Tim Newsome 87c90393fe Cleanup of config/includes.
Remove a use of AH_BOTTOM from configure.ac. This macro is used by
autoheader to add '#include' of some include file to the end of
config.h.in and then to config.h. OpenOCD can be built with a custom
config.h, so it's preferable to move these '#include' statement directly
in the C files that need them dropping this unneeded dependency.

It also causes problems when I want to use the gnulib library (which
comes with its own Makefile, and does not have the same include path as
the top-level Makefile).

So this change touches a lot of files, but is actually really simple. It
does not affect functionality at all.

- write speed up to 150 kByte/s on STM32F469I-disco (due to
  SWD clock and USB connection), up to 1 MByte/s on Nucleo-F767ZI
  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
  STM32L476G-Disco (all 128Mbit flash, 3-byte addr),
  STM32F723E-Disco, STM32F769I-Disco (512Mbit flash, 4-byte addr)
  STM32L4R9I-Disco, STM32L4P5G-Disco (512MBit octo-flash, DTR, 4-byte addr)
  STM32H745I-Disco, STM32H747I-Disco (two 512MBit flash, 4-byte addr)
  STM32H73BI-Disco, STM32H735G-Disco (512MBit octo-flash, DTR, 4-byte addr)
- 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.

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.

3. Add target_get_gdb_reg_list_noread() so it's possible for gdb to get

In commit bb9d9c6026, the
`get_target_by_num` call was replaced by a `get_current_target` call,
without noticing that `get_current_target` aborts if there is no current
target, whereas `tcl_new_connection` is perfectly able to handle that
situation.

Provide a `get_current_target_or_null` function for use by consumers who
are OK with a null current target, and use it in `tcl_new_connection`.

Antonio Borneo ab858febb6 gdb_server: add per target option "-gdb-port"
The argument passed to global config command "gdb_port" is usually,
but not always, a TCP port number. In case of multiple targets, this
numeric value is used as the first port of a set of consecutive TCP
ports assigned one per target.
If the argument is not a numeric value (e.g. "pipe", "disabled", ...)
then incrementing it for the next target has no sense.

Add the option "-gdb-port number" to the commands "target create" and
"$target_name configure" to override, for the specific target, the
general global configuration.

This permits to use a per target "-gdb-port disabled", when no gdb
port is required for that specific target.

It also makes possible to choose a custom TCP port number for each
target, overriding the usual sequence of consecutive port numbers.

Tomas Vanek eb8912ec38 target, flash: prepare infrastructure for multi-block blank check
'flash erase_check' command runs a check algorithm on a target
if possible. The algorithm is run repeatedly for each flash sector.
Unfortunately every start and stop of the algorithm impose not negligible
overhead.
In practice it means checking is faster than plain read only for
sectors of size approx 4 kByte or bigger. And checking sectors
as short as 512 bytes runs approx 4 times slower than plain read.

The patch changes API call target_blank_check_memory() and related
to take an array of sectors (or arbitrary memory blocks).

Changes in target-specific checking routines are kept minimal.
They use only the first block from the array and process it by
the unchanged algorithm.

default_flash_blank_check() routine repeats target_blank_check_memory()
until all blocks are checked, so it works with both multi-block
and single-block based checkers.

Extend the CTI abstraction to be accessible from TCL and
change the 'target' command to accept a cti 'object' instead of a
base address. This also allows accessing CTI instances that are not
related to a configured target.

Some vendors don't fully populate the ROM table, e.g. BCM2357 (used in
Raspberry Pi 3) doesn't list CTI, however it is mandatory for halting
an ARMv8 core and therefore it's always present (and required),
regardless of the ROM table listing it or not.

Dongxue Zhang 47b8cf8420 target: Add 64-bit target address support
Define a target_addr_t type to support 32-bit and 64-bit addresses at
the same time. Also define matching TARGET_PRI*ADDR format macros as
well as a convenient TARGET_ADDR_FMT.

In targets that are 32-bit (avr32, nds32, arm7/9/11, fm4, xmc1000)
be least invasive by leaving the formatting unchanged apart from the
type;
for generic code adopt TARGET_ADDR_FMT as unified address format.

Don't silently change gdb formatting here, leave that to later.

Add COMMAND_PARSE_ADDRESS() macro to abstract the address type.
Implement it using its own parse_target_addr() function, in the hopes
of catching pointer type mismatches better.

Add '--disable-target64' configure option to revert to previous 32-bit
target address behavior.

Matthias Welwarsky 53a936afc0 Add -defer-examine option to target create command
The '-defer-examine' option to target create allows declaring targets
that are present on the chain, but not fully functional.  They will
be skipped by the initial arp_examine as well as arp_examine after
reset.

Manual examine using 'arp_examine' is needed to examine them, with the
idea that some kind of actions is neeed to bring them to a state where
examine will succeed (if at all possible).

In order to allow value less options to target command, I had to relax
the goi.argc check in jim_target_configure().

Andreas Färber eaacb900dd flash/nor: Add erased_value to drivers and pass it to targets
struct flash_driver has a default_padded_value field that is similar,
but it can be changed by the user for the specific purpose of padding.

Add a new erased_value field and initialize it for all targets,
particularly stm32lx, xmc4xxx and virtual.

Use this value in core.c:default_flash_mem_blank_check(), the slow path.

Extend the target API to pass erased_value down to target code.
Adding an argument ensures that we catch all callers.

This allows us to merge xmc4xxx.c:xmc4xxx_blank_check_memory() into
armv7m:armv7m_blank_check_memory().

It further allows us to use default_flash_blank_check() in place of
xmc4xxx.c:xmc4xxx_flash_blank_check(), adding a potential slow path
fallback, as well as stm32lx:stm32lx_erase_check(), adding the potential
armv7m fast path with fallback to default_flash_mem_blank_check().

Fix a mips32 code comment while at it (zeroed -> erased).

The armv4_5 and mips32 target implementations will now error out if an
erase value other than 0xff is used, causing default_flash_blank_check()
to fall back to the default_flank_mem_blank_check() slow path.

Andreas Färber f19ac83152 Fix usage of timeval_ms()
First, fix the timeval_ms() implementation to not have K&R but ANSI
argument semantics by adding a missing void.

timeval_ms() returns an int64_t, not uint64_t or long long. Consistently
use int64_t for variables and PRI*64 as format string.

While at it, change a few related variables to bool for clarity.

Note that timeval_ms() may return a negative error code, but not a
single caller checks for that.

there're also many blocks from TCL command registration.

Paul Fertser b71ae9b1a7 target: fix timer callbacks processing
Warning, behaviour change: before this patch if a timer callback
returned an error, the other handlers in the list were not called.

This patch fixes two different issues with the way timer callbacks are
called:

1. The function is not designed to be reentrant but a nested call is
possible via: target_handle timer event -> poll -> target events
before/after reexaminantion -> script_command_run ->
target_call_timer_callbacks_now . This patch makes function a no-op
when called recursively;

2. The current code can deal with the case when calling a handler
leads to its removal but not when it leads to removal of the next
callback in the list. This patch defers actual removal to consolidate
it with the calling loop.

These bugs were exposed by Valgrind.

Andreas Fritiofson 1c021ed0af target: Remove "-variant" argument
Remove this underutilized feature. Despite the fact that a lot of configs
specifies a arbitrary "variant", only the xscale target actually defines
any.

In the case of xscale, the use of -variant is dubious since

1) it's used as a redundant irlen specifier,
2) it carries a comment that it doesn't really need it and
3) only two xscale configs even specify it.

If there's a future target that needs a variant set, a target specific
option could be added when needed.

Andreas Fritiofson 17fddb4289 stlink: Use callback to increase frequency of trace data sampling
The ST-LINK/V2 has limited internal buffering, such that trace data
can be missed if the target is generating data at a rate quicker than
the OpenOCD trace sampling. The issue of lost data is compounded since
individual TPIU packets may be split across individual STLINK_TRACE_EP
reads, and misleading results can occur if mid-packet loss occurs.

This patch increases the frequency of checking for pending trace data
with the aim of minimising such losses. Note: With the limited (I/O
and memory) bandwidth of the ST-LINK/V2 there cannot, however, be a
guarantee against trace data loss.

The timer callback is only added when enabling tracing, and is removed
when tracing is disabled.
