Antonio Borneo 80ce68b42c stlink: simplify api version handling
The API version is hardcoded in the STLINK device and depends on
the specific firmware version. There is no way to switch between
different API. Thus, it make no sense to keep in two separate
variables the current and the max API supported because they are
always equal to "the only" API supported by the specific STLINK.

Collapse h->version.jtag_api_max and h->jtag_api in a single
variable h->version.jtag_api
Remove an extra print of api version; this is already advertised
while printing the STLINK version.

Antonio Borneo 9252a94218 stlink: simplify maintenance of version and features
The number of stlink firmware version is growing, each carrying new
features. Today's code has several check distributed here and there
and it's already hard to track them and verify the correctness.
The introduction of STLINK-V3 will make the situation much worst,
and the code much less readable.

Add a "flags" bitmask in the struct stlink_usb_version to allow
setting individual bits for each feature available or for specific
quirks and workarounds.
This patch does not implement setting nor testing "flags"; it would
be introduced in following patches, one bit at a time.

In previous versions of OpenOCD, it was possible to connect to the TCL

In commit bb9d9c6026, the
`get_target_by_num` call was replaced by a `get_current_target` call,
without noticing that `get_current_target` aborts if there is no current
target, whereas `tcl_new_connection` is perfectly able to handle that
situation.

Provide a `get_current_target_or_null` function for use by consumers who
are OK with a null current target, and use it in `tcl_new_connection`.

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.

Antonio Borneo fac9be64d9 target/cortex_a: remove buggy memory AP accesses
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.

Handle write protection status in blocks instead of sectors, removing
unnecessary complexity in the process. Now closer to stm32f2x.
Support sequential modification of option bytes by read/modify/write
directly to option bytes area instead of always starting with the
currently loaded bytes from FLASH_OBR/WRPR registers.
Added new command 'options_load' to force re-load of option bytes w/o
having to power cycle target.

Antonio Borneo 1e3ba2046c arm_adi_v5: do not deactivate power domains while trying to clear sticky error
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.

Tomas Vanek da4b2d5beb drivers/cmsis-dap: speed up sending multiple HID requests
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:

Antonio Borneo cf81de7052 target/cortex_a: fix temporary breakpoint during step
Commit c8926d1457 introduces the
context and hybrid breakpoint types beside existing SW and HW
types. The new field "asid" is non-zero only for these new types.

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().

Fixes: c8926d1457 ("cortex_a hybrid & context breakpoints")

Antonio Borneo 1ba715422f target/arm_adi_v5: fix sync CSW cache on apreg write
Commit 0057c71ab6 updates the OpenOCD
cached values of CSW and TAR registers if these registers are modified
by an apreg command.
The condition to force the update of CSW cache is incorrect and it will
erase the default CSW value.
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
directly in CSW register the new value from the command line.
