Tim Newsome 4e6fe83f83 remote bitbang, flush resets.
Waiting until the next execute_queue() might mean the target doesn't see
the reset signal asserted for a significant amount of time.

ARRAY_SIZE and unused variable

Antonio Borneo 9bdd1daec3 riscv: replace macro DIM() with ARRAY_SIZE()
OpenOCD already defines the macro ARRAY_SIZE, while riscv code
uses a local macro DIM.

Prefer using the macro ARRAY_SIZE() instead of DIM().
Not all the riscv code has been upstreamed, yes; this patch only
covers the code already upstreamed.

Antonio Borneo bbbfddc3ef jimtcl: restrict memory leak workaround on Linux only
The workaround for jimtcl 0.80 in commit 36ae487ed0 ("jimtcl:
add temporary workaround for memory leak in jimtcl 0.80") issues a
compile time error on macOS:
	../src/helper/command.c:157:22: error: aliases are not
	supported on darwin
	__attribute__((weak, alias("workaround_createcommand")));
The OS is x86_64-apple-darwin19.6.0 and the compiler used is
x86_64-apple-darwin13.4.0-clang.

Restrict the workaround on Linux host only. The fix for 'expr'
syntax change is already merged and the workaround will be dropped
soon.

Evgeniy Didin 77b28ced14 rtos: Add support for Zephyr RTOS
With this patch, the Zephyr[1] RTOS is supported by OpenOCD.

As usual with support for other RTOSes, Zephyr must be compiled with
the DEBUG_THREAD_INFO option. This will generate some symbols
with information needed in order to build the list of threads.

The current implementation is limited to Zephyr running on ARM
Cortex-M processors. This is the only ARM variant supported by Zephyr
at the moment and is used on most of the officially supported boards.

Peter Lawrence b60d06ae32 tcl/board: add pico-debug support
pico-debug is not a board; it is a virtual CMSIS-DAP adapter that
runs on the same RP2040 also being debugged.  This is possible due
to pico-debug running on the normally-dormant second Cortex-M0+
core (Core1), providing debugging of the first core (Core0).
As such, it could be used on a variety of RP2040-based boards.

Since a flash driver is useful (if not essential), a flash driver
is included.  This driver code originated on RPi's bespoke OpenOCD
fork; lipstick was added to this particular pig to make it more
presentable on OpenOCD proper.

asier70 64a3e7ba4f flash/nor/stm32f1x: Add support for GD32F1x0/3x0
Nowadays, when it's difficult to buy STM32F030,
the use of GD32F130 seems to be an interesting functional alternative.
This is cortex-M3 and it works with the stm32f1x driver, but unfortunately not fully.
The main difference is another offset of user option bits
(like WDG_SW, nRST_STOP, nRST_STDBY) in option byte register
(FLASH_OBR/FMC_OBSTAT 0x4002201C).
Any use of functions like lock or unlock results in change default values of the those bits stored in flash.
Thus broken microcontroller is malfunctioning, e.g. flash block programming is interrupted
by unexpected active hardware watchog (after 0.4s).
This patch is a simplified version of #4592 done by Dominik Peklo (http://openocd.zylin.com/#/c/4592/).
GigaDevice GD32F1x0 & GD32F3x0 series devices share DEV_ID
with STM32F101/2/3 medium-density line,
however they use a REV_ID different from any STM32 device,
so can be succesfully detected.

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.

Luis de Arquer b44948985f drivers/ftdi: drscan: Skip DR-PAUSE when endstate == IDLE
Currently, all drscan commands will cycle through DR-PAUSE before reaching
TAP-IDLE. This patch provides a different path on FTDI driver.

This change is required for the ST On Chip Emulator (OnCE), to avoid
re-enabling the OnCE tap after every DRSCAN. This is because the OnCE
TAP (see ST Application Note AN4035) gets disabled if DR-PAUSE is entered
before DR-UPDATE.

With this commit, the current path:

DR-SHIFT -> DR-EXIT1 -> DR-PAUSE -> DR-EXIT2 -> DR-UPDATE -> IDLE

is changed to:

DR-SHIFT -> DR-EXIT1 -> DR-UPDATE -> IDLE

only if IDLE is the endstate (which is the driver default).

Before this patch, once the SHIFT sequence is complete, the driver would
normally move to the nearest stable state, which is DR-PAUSE, by clocking
out a '10' binary sequence. Then it would follow the path provided by
tap_get_tms_path() to reach endstate. It is done this way because
tap_get_tms_path() only supports stable states.

After this patch, the strategy is mostly the same, with the exception that,
if TAP_IDLE is the endstate, a '110' binary sequence is output after completing
the SHIFT sequence. This takes the TAP directly to IDLE, with no further action
required.

A scheme of the DR chain is shown below. A * character is used to mark the
stable states.

The documentation of Jim_SetResultFormatted() reports that the jim
objects passed as arguments would be freed if have zero refcount.

Remove the useless Jim_IncrRefCount()/Jim_DecrRefCount().
Remove the dangerous Jim_FreeNewObj() that should trigger a double
free(). Not tested due to lack of aice adapter.

While there, rename some CamelCase symbol.

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'.

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().
