STLINK-V3 and the new firmware V2J24 for ST-LINK/V2 provide API
to directly access the DAP registers.
This mode permits to use the native target in cortex_m.c, with no
need to override it with the target in hla_target.c.
Other advantages wrt HLA are: support for Cortex-A cores, support
for SoC multi-core and/or multi AP, support for OpenOCD commands
"dap" thus including control of CSW.
This obsoletes the existing HLA driver for ST-Link, that should
anyway be kept for those cases where it's not possible to update
the ST-Link firmware.
This commit introduces the minimal implementation for direct DAP
access. The implementation is much slower than the HLA because
every memory transfer requires several USB packets. Further
commits will close the performance gap.
The whole ST-Link driver is compiled under BUILD_HLADAPTER, to
remove the need to split the driver between the two modes. This
has to be reworked, but it's quite invasive!
A new interface file stlink-dap.cfg is added and should be used
in place of stlink.cfg to enable the DAP mode.
Documentation is updated and reports limitation on the maximum AP
number that can be accessed by ST-Link for some firmware already
tested.

Issue has been found when I tried to read 64 MiB QSPI flash bank.
Bank is memory mapped, default_flash_read() is used for 'flash read_bank'
command. OpenOCD consumed as much as 6.8 GiB of RAM during this
process. Investigation showed that this happens because JTAG queue
is not limited in any way. OpenOCD queues 16 millions of AP reads
allocating all corresponding data structures.
Most of this memory is allocated in:
cmd_queue_alloc (commands.c) - 4.2 GiB
dap_cmd_new (adi_v5_jtag.c) - 2.25GiB
This patch implements a pool of "struct dap_cmd" objects using
linked list. Objects are taken from a pool in "dap_cmd_new()" and
returned to the pool when they are not needed. Size of the pool
is limited to 64K of objects, JTAG queue is forcibly executed
when this limit is reached.
Checked with Valgrind and Clang analyzer - no new warnings.

Later, in 6f8b8593d6 ("ADIv5 transport support moves to separate

"target" with "dap", use the transport to detect if the JTAG queue is

transports report error.

When SWD mode is used, current OpenOCD code left the SWJ-DP in
SWD mode at exit. Also, current code is unable to switch back the
SWJ-DP in JTAG at next run, thus a power cycle of both target and
interface is required in order to run OpenOCD in JTAG mode again.
Put the SWJ-DP back to JTAG mode before exit from OpenOCD.
Use switch_seq(SWD_TO_JTAG) instead of dap_to_jtag(), because the
latter is not implemented on some interfaces. This is aligned
with the use of switch_seq(JTAG_TO_SWD) in swd_connect().

This patch implements WAIT handling by keeping a journal of all

Fix bug in parity calculation macro.
Cache and update the selected DP bank when necessary.
Add aborts when the Ack code signals a failure (we should really only
clear the sticky bits, but this will do for now).

Previous to this commit 'ahbap_debugport_init' would ignore if timeout
happened or not when waiting for CDBGPWRUPACK and CSYSPWRUPACK and would
continue initialization regardless. It also would not reset the
timeout counter after finishing polling for CDBGPWRUPACK and starting
for CSYSPWRUPACK which could potentially cause some problems.
Also refactor code of both snippets into a more generic function to
avoid duplication.

The TI TMS470 and TMS570 series of processors are BE-32 processors,
despite BE-32 not being supported by ARM in the Cortex-R4 core. TI
hacked in BE-32 support, which requires odd swizzling in OpenOCD to
make memory reads and writes function correctly. In particular,
without this change, OpenOCD word reads and writes had the bytes
reversed, and halfword and byte packed reads were reading garbage.
In my testing, this change fixes these problems.

It's far nicer to pass a size parameter than to split the calls to
separate wrappers which are combined to a single function anyway.

This eliminates most of the warnings reported when building for
arm-none-eabi (newlib).
Hsiangkai, there're many similar warnings left in your nds32 files, I
didn't have the nerve to clean them all, probably you could pick it
up.

Create a single pair of relatively simple functions to handle all variants
of MEM-AP transfers. This replaces the many separate functions that
handled different access sizes and packed or non-packed transfers, which
were all implemented rather differently.
With this single implementation, performance should be more consistent,
regardless of transfer type.
