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.

Erase is initiated by write to a flash address. Due to the
silicon errata of nRF91 the write stalls the bus until the page erase
is finished (takes up to 87ms).
If the adapter does not handle SWD WAIT properly, the following read
in nrf5_wait_for_nvmc() returns ERROR_WAIT.
Wait for fixed time before accessing AP. Not nice, but the only
working solution until all adapters handle SWD WAIT.
If the fixed wait does not suffice, continue the wait loop after a delay.
It makes some unnecessary noise however erase works.

Commit 236c54c94a ("server/gdb_server.c: support unavailable
registers") correctly returns a string of 'x' when the register is
not available in the current target.
While implementing this, it incorrectly drops the pre-existing
feature of optionally ignoring errors while reading a register.
This feature has a real use case documented in the OpenOCD manual
in chapter 'Using GDB as a non-intrusive memory inspector', where
GDB attaches to a target without halting it. For targets that need
to be halted to read its registers, we need to hack the values of
the registers returned to GDB; either returning 'xxxx' or an error
causes GDB to drop the connection.
Re-add the check on 'gdb_report_register_access_error' to keep the
pre-existing behavior when a register error has to be ignored:
- return a string of '0';
- drop a debug message.

clang doesn't support the gnu_printf attribute that OpenOCD uses if
__GNUC__ and __GNUC_MINOR__ indicates gcc >= 4.4.
Most clang builds set __GNUC__/__GNUC_MINOR__ to 4.2 for historical
reasons, so they don't trigger this condition; however, some builds set
it to something much higher to work around code using __GNUC__ to
determine if a feature that does exist in clang (but not gcc 4.2) is
available, causing OpenOCD to use attribute gnu_printf.
The problem can be reproduced without a special clang build by adding
-fgnuc-version=14.1 to CFLAGS.

The handling of cache for cortex_a is robust and there is no more

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.

Add some helpers for booting ZynqMPs over JTAG. Normally, the CSU ROM
will load boot.bin from the boot medium. However, when booting from JTAG
we have to do this ourselves. There are generally two parts to this.
First, we need to load the PMU firmware. Xilinx's tools do this by
attaching to the PMU (a Microblaze CPU) over JTAG. However, the TAP is
undocumented and we don't have any microblaze support in-tree. So
instead we do it the same way FSBL does it:
- We ask the PMU to halt
- We load the firmware into the PMU RAM
- We ask the PMU to resume
The second thing we need to do is start one of the APU cores. When an
APU is released from reset, it starts executing at the value of its
RVBARADDR. While we could load the APU firmware over the AXI target,
it is faster to load it over the APU target. To do this, we put the APU
into an infinite loop before halting it. As an aside, I chose to use the
"APU" terminology as opposed to "core" to make it clear that these
commands operate on the A53 cores and not the R5F cores.
Typical usage of these commands could look something like
targets uscale.axi
boot_pmu /path/to/pmu-firmware.bin
boot_apu /path/to/u-boot-spl.bin
But of course there is always the option to call lower-level commands
individually if your boot process is more unusual.

The gdb subsystem is initialized after the first target examine,
so the field struct target::gdb_service is NULL during examine.
A command "smp off" in the examine event handler causes a SIGSEGV
during OpenOCD startup.
Check for pointer not NULL before dereferencing it.

The code for cortex_a allocates the register cache during the very
first examine of the target.
To prevent a segmentation fault in assert_reset(), the call to
register_cache_invalidate() is guarded by target_was_examined().
But for targets with -defer-examine, the target is set as not
examined in handle_target_reset() just before entering in
assert_reset().
This causes registers to not be invalidated while reset a target
examined but with -defer-examine.
Change the condition and invalidate the register cache if it has
been already allocated.
