Antonio Borneo a3b69dee62 jtag/aice: switch to command 'adapter serial'
The driver aice defines the command 'aice serial' to specify the
serial string of the adapter, but actually does not use this value
in the code.

Remove and deprecate the driver command, and use 'adapter serial'.

Antonio Borneo 0343ae7cc7 jtag/adapter: add command 'adapter serial'
Several adapter define their own command to specify the USB serial
number or serial string to be used during USB search.

Define a general command 'adapter serial' to be proposed as
replacement of the driver specific ones.
No driver is changed so far to use it.

Tomas Vanek f66a16c4a0 target/hla_target: set cortex_m->common_magic
hla_target uses the same struct cortex_m_common as the standard cortex_m
target. Unlike the cortex_m target hla missed setting of common_magic.

Set commont_magic to help pointer verification.

Add convenience tests is_cortex_m_or_hla() and
is_cortex_m_with_dap_access()

Use proper test in cortex_m_verify_pointer() - this code relied on
unset common_magic on hla target before the change.

Deal with halt race. (#664)
* Deal with halt race.

What could happen:
1. hart 1 halts due to a breakpoint
2. OpenOCD polls and notices hart 1 has halted.
3. hart 0 halts because it is in a halt group with halt 1
4. OpenOCD decides to halt hart 0 also.
5. OpenOCD discovers hart 0 is already halted, and doesn't update the
debug reason.

In that case OpenOCD would tell gdb that hart 0 halted, while the
interesting event is that hart 1 halted.

Fix this by updating the debug reason when we discover a hart is already
halted when we try to halt it.

This race was exposed in the Sv* address translation tests, but the bug
has nothing to do with address translation.

Tomas Vanek d203399787 target/adi_v5_swd: add support for SWD multidrop
Based on Graham Sanderson's http://review.openocd.org/4935

Unlike Graham Sanderson's version this patch does not add
any multidrop specific queuing.

Multidrop SWD is handled mostly by the same code as single SWD,
just a selection sequence is prepended to a SWD operation
as needed.

This is a minimal working implementation without checking for
configuration errors (mixing multidrop and non multidrop DPs,
multiple use of the same selection id etc...).

Multidrop switching likely demands changes in the adapter code.

Andreas Fritiofson caa1698136 cortex_m: Restore fast register reads if no polling is needed
If the target is in a state where S_REGRDY polling is necessary (slow
clock, low power state...?), OpenOCD will continue to use the slow
path even if the condition is temporary and the target at a later
point would be capable of fast reads again.

Revert to fast reads if a full register dump can be made without need
for polling any of the registers; presumably it will succeed the next
time too.

a poor usage of JTAG/SWD queue.
It is time consuming, especially on an USB FS based adapter.
Moreover if target_request debugmsgs are enabled, DCB_DCRDR
is saved and restored on each register read.

This change introduces cortex_m_fast_read_all_regs()
which queues all register reads and a single dap_run() transaction
does all work.

cortex_m_fast_read_all_regs() reads all registers unconditionally
regardless register cache is valid or not. This is a difference
from the original cortex_m_debug_entry() code.

cortex_m_debug_entry times from -d3 log, Cortex-M4F and CMSIS-DAP
(Kinetis K28F-FRDM kit)

target_request |                time [ms]
debugmsgs      | without the change | with the change
---------------+--------------------+-----------------
disable        |        186         |       27
enable         |        232         |       29

Added checking of DHCSR.S_REGRDY flag. If "not ready" is seen,
cortex_m->slow_register_read is set and fallback to the old
register read method cortex_m_slow_read_all_regs() is used
instead of cortex_m_fast_read_all_regs().

Antonio Borneo 65d7629183 cortex_m: poll S_REGRDY on register r/w
Accordingly to arm documentation [1], chapter C1.6.4, the
operation to read/write from/to core registers can require time,
and the specific flag DHCSR.S_REGRDY has to be polled to verify
that the operation has been completed.
The lack of check on S_REGRDY causes OpenOCD to fail handling
correctly the core registers on a Cortex-M4 emulated in a slow
FPGA, and it could also fail on devices clocked at very low speed
while using a fast adapter.

Poll S_REGRDY as specified in [1] while either reading or writing
the core registers.
A timeout of 0.5s is added. This could still be too small in some
extremely slow cases, but at least now we log the timeout event,
which can help tracking down such odd issue.
During register read include in the polling loop the read of DCRSR
and to flush the JTAG queue only once.
During register write, relax the write in DCRSR by removing the
atomicity that is now useless since followed by the atomic read to
S_REGRDY.
During register read include the read of DCRSR inside the polling
loop to relax the read of S_REGRDY since followed by the atomic
read to DCRSR.

This change has the drawback of adding other transfers to the
adapter while reading/writing the registers, so it is expected to
introduce some speed degradation during step-by-step.

Tomas Vanek 0dcf95c717 target/cortex_m: cumulate DHCSR sticky bits
DCB DHCSR register contains S_RETIRE_ST and S_RESET_ST bits cleared
on a read.

The change introduces a helper function cortex_m_cumulate_dhcsr_sticky().
Call this function each time DHCSR is read to preserve S_RESET_ST state
in the case of a reset event was detected.

Introduce cortex_m_read_dhcsr_atomic_sticky() convenience helper to
read DHCSR, store it to cortex_m->dcb_dhcsr and cumulate sticky bits.

The cumulated state of S_RESET_ST is read and cleared in cortex_m_poll()

GD32E23x from GigaDevice is cortex-M23 microcontroller and it can work with the stm32f1x driver.
Modifications are similar to this done for GD32F1x0 in #6164 (https://review.openocd.org/c/openocd/+/6164).
Configuration file is added because its cortex-M23 CPU ID is different.
I think that GigaDevice microcontrollers should be handled in an independent unit to separate them from STM32,
but nowadays quick solution is welcome.

Jan Matyas a4f8bf7a90 helper/log: Add macros for target-related errors/warnings/...
This commit introduces macros for target related log entries
(error, warning, ...) which is a very common operation in OpenOCD:

* LOG_TARGET_ERROR
* LOG_TARGET_WARNING
* LOG_TARGET_INFO
* LOG_TARGET_DEBUG
* LOG_TARGET_DEBUG_IO

The goal is to have one macro for this common operation and to
make such log entries look the same way - to make it more readable
for humans as well easier for parsing via scripts.
