The stm32h7x.cfg does not specify connect_assert_srst or
connect_deassert_srst in its reset_config. The comment claims that it
will therefore connect in reset. However, per the manual, the default
configuration is actually connect_deassert_srst, not
connect_assert_srst. In actual fact, connect_assert_srst does not work
on the STM32H7 because, while SRST is asserted, everything on the AXI
bus is inaccessible. The CPU core is accessible, but since the
examine-end event handler also pokes at the DBGMCU peripheral, that will
fail in connect_assert_srst mode. So using connect_deassert_srst is
appropriate, so fix the comment accordingly.

The armv7m debug port provides a direct access to the CPU memory
bus, allowing the debugger to bypass the CPU for every memory
operation.
The armv7a debug port doesn't offer the same feature, mainly
because CPU caches and MMU makes the direct memory access more
tricky. Nevertheless most SoC with armv7a provide direct memory
access through an AHB bus available on another DAP access port,
different from the debug port.
The original port of cortex_a in OpenOCD was inspired from the
working cortex_m code, and provided optional memory access
through the AHB, if present.
The code for AHB access is problematic and partially buggy due
to incomplete management of cache coherency and missing check of
page boundary during virtual address operations.
With the commit 5d458cf727
("target/mem_ap: generic mem-ap target") we have a clean support
for memory access through system buses connected to DAP AP, which
obsoletes the buggy memory AP hack in cortex_a.
Remove any code that uses the memory AP accesses in cortex_a.

At OpenOCD start-up the operation of clearing the sticky error in
CTRL/STAT register ignores the current value of the power domains
bits CDBGPWRUPREQ and CSYSPWRUPREQ in the same register and
incorrectly set them to zero.
This abrupt disable does not follow the requirement in IHI0031 to
wait for the acknowledgment of power disabled before continuing.
The power domains are then re-enabled immediately after; it is
possible that such short disable period has passed undetected or
has been tested only on devices that do not implement the power
domains.
Anyway, this sequence is incorrect and can generate unexpected
and hard-to-debug issues while OpenOCD attaches to a running
target that implements power domains.
Anticipate the initialization of dap->dp_ctrl_stat and use it
while clearing the sticky bit. This has the additional effect of
avoiding a power disable in the error recovery part of the
function dap_dp_read_atomic().
Keep the same sequence of read/write in dap_dp_init() to avoid
breaking the initialization of some problematic target.
Add comments to document these choices.

The performance of CMSIS-DAP in long data transfers was improved substantially in
ef02b69b14. But it not as good as some
other USB/MCU based adapters. Using HID and therefore interrupt endpoint
is slower than USB bulk transfer.
CMSIS-DAP adapter implements multiple HID buffer handling and OpenOCD already
reads number of buffers from info command.
This change adds capability to sumbit more than one HID requests before
driver waits for a HID response. This scenario is used for long transfers only.
Results show about double speed on USB FS and ~140% speed on USB HS:

Commit c8926d1457 introduces the

The commit above did not properly initialize "asid" to 0 for a
temporarily HW breakpoint used during single step. This causes
cortex_a_unset_breakpoint() to identify this breakpoint as of
type "hybrid".
Identified through valgrind error:
Conditional jump or move depends on uninitialised value(s)
Actually valgrind triggers a total of 10 messages about use of
uninitialized variables, but they are all caused by the first
conditional jump bases on "asid != 0".
Fixed by initializing "asid" to 0 in cortex_a_step().

The condition to force the update of CSW cache is incorrect and it will

Moreover, calling mem_ap_setup_csw() does not honor the value requested
in the apreg command because such value is incorrectly bitwise or-ed
with csw_default.
Fix it by updating csw_value, instead of erasing csw_default, and writing
