The command 'gdb_report_register_access_error' is used to silence
errors while reading registers and not reporting them to GDB.
Nevertheless, the error is printed by a LOG_ERROR() in armv8_dpm.
Change the message to LOG_DEBUG().
It will still cause the error to be propagated and eventually
printed by the caller (e.g. by the command 'reg').

cortex_m_poll_one() detects reset testing S_RESET_ST sticky bit.
If the signal comes unexpectedly, poll must return TARGET_RESET state.
On the contrary in case of polling inside of an OpenOCD reset command,
TARGET_RESET has been has already been set and we need to get out of
it as quickly as possible.
The original code needs 2 polls: the first clears S_RESET_ST
and keeps TARGET_RESET state, the current TARGET_RUNNING or TARGET_HALTED
is reflected as late as the second poll is done.
Change the logic to keep in TARGET_RESET only when necessary.

The initial OpenOCD code for Cortex-A (ARMv7a) [1] was merged in
2009 but, due to lack of public documentation for ARMv7a, it was
almost a simple copy/paste from the existing code for Cortex-M
(ARMv7m).
On Cortex-M the same AP provides access to both CPU debug and CPU
memory. This feature is not present on ARMv7a.
To still keep some communality with ARMv7m code, the change [2]
splits the CPU debug access from the CPU memory access by using
two independent AP; this is copied from the system architecture of
TI OMAP3530 which provides to DAP a direct AHB-AP memory bus on
AP#0, separated from AP#1 for the APB-AP CPU debug.
But the direct memory access through the system bus breaks the
coherency between memory and CPU caches, so change [3] added some
cache invalidation to avoid issues.
The code to allow ARMv7a CPU to really read/write in CPU memory
was added by change [4] in 2011. Such still not optimized
implementation was very slow, so it did not replace the access
through the system bus. A selection through DAP's 'apsel" command
was used to select between the two modes.
Only in 2015, with change [5], the speed of CPU read/write was
improved using the DCC_FAST_MODE. But the direct access to the
memory through the system bus remained.
Finally, with change [6] in 2018 the system bus access was dropped
for good, as the new virtual target "mem_ap" could implement such
access in a more clean way.
Only memory access through CPU remained for ARMv7a.
Nevertheless, a useless cache invalidation remained in the code,
decreasing the speed of the write access.
Drop the useless cache invalidate on CPU memory write and the
associated comment, not anymore valid.
Drop the now unused function armv7a_cache_auto_flush_on_write().
This provides a speedup of between 4 and 8, depending on adapter
and JTAG/SWD speed.

ADIv6 brought more complicated rules for DP reg 0 banking.
Neither the original implementation [1] nor the later
modification [2] respected that the DP reg 0 is banked
for read only, not for write. Enforcing of an useless
SELECT write before a write to ABORT register may trigger
FAULT (CTRL/STAT bits ORUNDETECT and STICKYORUN are set)
or WAIT (DP is stalled by an outstanding previous operation)
and therefore make ABORT register virtually unusable
on some adapters (bitbang, CMSIS-DAP).
There are DP ABORT specific functions swd_queue_ap_abort()
and swd_clear_sticky_errors() which worked around the problem
using the lowest level swd->write_reg(). Using a specific
write procedure for a single DP register was error prone
(there are other DP_ABORT writes using swd_queue_dp_write_inner())
and also the Tcl command 'xx.dap dpreg 0 value' suffered
from unwanted SELECT write.
Other smaller discords in DP banking probably do not
influence normal DP operation however they may complicate
debugging in corner cases.
Adhere strictly to the DP banking rules for both ADI versions.

In 2008 the commit 1829361253 ("define resetting

introduced the target_halt() call to the end of cortex_m3_assert_reset(),
Checkpatch-ignore: GIT_COMMIT_ID
A year later the commit ed36a8d15d
("... Updated halt handling for cortex_m3")
prevented cortex_m3_halt() take any action in case of TARGET_RESET state.
This narrowed the target_halt() called from cortex_m3_assert_reset()
to setting target->halt_issued and storing a time stamp.
Introducing ocd_process_reset(_inner) made the setting of halt_issued
and halt_issued_time useless. The Tcl function waits for halt
of all targets if applicable.
cortex_m_halt() and also target_halt() does not work as expected
if the cached target state is TARGET_RESET (although the core could
be out of reset and ready to be halted, just have not been polled).
Explicit Tcl arp_poll must be issued in many scenarios.
Remove the useless hack.
Also remove the explicit error return from cortex_m_halt_one()
in case of RESET_SRST_PULLS_TRST and asserted srst. If the communication
with the target is gated by any reset, cortex_m_write_debug_halt_mask()
fails. Propagate the error return of this call instead.

The target esirisc does not free the allocated memory resources,
causing memory leaks at OpenOCD exit.
Add esirisc_free_reg_cache() and esirisc_deinit_target() and use
them to free all the allocated resources.

The function in question does not need to change target state. It is a
target-type-dependant function, however, IMHO, it is safe to assume that
any target type would not need to change type-independant state of a
target to figure out the arch.

There are quite a lot of "getters" in target interface.
They do not change target structure, nevertheless the structure is
passed to these functions via a plain pointer.
The intention is to clarify the purpouse of these functions by passing
the `target` structure as a pointer to constant data.

The function is used for commands:
- jtag configure
- jtag cget
While there, add the missing .usage field.

clang build triggers an error for an uninitialized value of the
variable 'instr'.
This is a false positive, as the macro
#define MIPS32_CONFIG3_ISA_MASK (3 << MIPS32_CONFIG3_ISA_SHIFT)
guarantees the switch/case already covers all the possible values
with cases 0, 1, 2 and 3.
Silent clang by adding a useless default case to the switch.
While there, fix the indentation of the switch/case accordingly to
OpenOCD coding style.

Commit e370e06b72 ("target: Deprecate 'array2mem' and
'mem2array''") has already replaced the deprecated root versions
of commands mem2array and array2mem with TCL proc's that use
'read_memory' and 'write_memory'. It has left the deprecated code
of the target's version of the commands because the effort to code
the TCL replacement was not considered valuable.
To drop the last jim_handler commands, I consider much easier and
less error-prone to code them in TCL instead of converting the
deprecated code to COMMAND_HANDLER.
Drop the code in target.c and extend the TCL proc's.
While there, add the TCL procs to _telnet_autocomplete_skip.

When requested by the core code (handle_breakpoints = true),
arc_resume() should be able to advance over a potential breakpoint set
at the resume address instead of getting stuck in one place. This is
achieved by removing the breakpoint, executing one instruction,
resetting the breakpoint, then proceeding forward as normal.
With this patch applied, openocd is now able to resume from a
breakpoint halt when debugging ARCv2 targets via telnet.
This has previously been committed to the Zephyr project's openocd repo
(see https://github.com/zephyrproject-rtos/openocd/pull/31).

Presently, we rely on gdb to restore break/watchpoints upon resuming
execution in arc_resume(). To match this behavior in absence of gdb
(more specifically, when handle_breakpoints is true), this patch
explicitly re-enables all breakpoints and watchpoints in arc_resume().
This has previously been committed to the Zephyr project's openocd repo
(see https://github.com/zephyrproject-rtos/openocd/pull/31).
