According to the datasheet, the minimum clock period with Vccio1 = 1.5V
(the lowest voltage supported) is 143ns, or around 6MHz. Set the default
adapter speed to 5 MHz.

Changed flash driver to support writing to the user data page, as well as to any portion of the lockbits page above 512 bytes (the amount used for the actual page lock words). The top part of the lockbits page is used on at least the EFR32xG1 chips for the SiLabs bootloader encryption keys.
As presented to the user, the lockbits page is the same size as the other pages, but any attempt to write to its low 512 bytes is an error. To enforce this, efr32x_write is renamed to efm32x_priv_write and a wrapper function is provided in its place. If the user erases the lockbits page, the driver rewrites the cached lock words after the erase. When the driver erases the lockbits page in order to update the lock words, it first takes a copy of anything stored in the top part of the page, and re-programs it after the erase operation.
There are now multiple instances of flash_bank for each target, and the flash_bank instances must share their cached lock words to operate as intended. Therefore, when a bank is created, the global flash bank list is used to find any other banks that share the same target. Since some banks in the global list are invalid at the time free_driver_priv is called, reference counting is used to decide when to free driver_priv.
To avoid the need to find the lockbits flash_bank from another flash_bank, efm32x_priv_write and efm32x_erase_page now take an absolute address.
There didn't seem to be any reason to prohibit unprotecting individual flash pages, so that limitation is removed from efm32x_protect().
This addresses ticket #185.

The driver xds110 defines the command 'xds110 serial' to specify
the serial string of the adapter.
Remove and deprecate the driver command, and use 'adapter serial'.
Note: the original command 'xds110 serial' used a complex and
undocumented conversion of the serial number through multibyte
string, wide-character string and C cast. The XDS110 I can access
and the lsusb dumps available through Google don't show any
exotic USB serial that require such conversion. The original
developer doesn't remember any constraint that mandates such
conversion (see comments in https://review.openocd.org/4322/).
The conversion is removed by this patch.

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.

Freeze the IWDG watchdog when cores are halted to prevent a reset
while debugging.
The PMIC present on some board senses the nsrst and forces a power
cycle to the target. The power cycle causes the SWJ-DP to restart
in JTAG mode. If the debugger is using SWD, the mismatch triggers
an error after the reset command.
Ignore the error detected by 'dap init' and proceed executing the
handler. The error in 'dap init' will force a reconnect during the
following 'dap apid', restoring the SWD functionality.

- 2MB variants are always dual bank
- 1MB and 512KB variants could be dual bank (contiguous addressing)
depending on DUALBANK bit(21)
- flash data width is 16 bytes (quad-word)

After compiling OpenOCD from source (commit: 6edf98db7), OpenOCD could not connect with the target board which is a GD32VF103T_START development board,
when I used the command: openocd -f "interface/cmsis-dap.cfg" -f "target/gd32vf103.cfg"
Issue 1: The clock speed hasn't been set, the error message given is:
Error: CMSIS-DAP command CMD_DAP_SWJ_CLOCK failed.
Which can be solved by adding a clock speed setting to the gd32vf103.cfg file:
adapter speed 1000
Issue 2: The default transport is not set to jtag, which it requires, the error shown is:

This issue can be solved by adding the line:

After adding these two lines, OpenOCD could connect to the development board successfully. Programming the flash also works.

according the RM0453, the second core have a different Flash CR and SR
registers for flash operations (called C2CR and C2SR).
so we need to a different flash_regs than older L4 devices.
@see stm32wl_cpu2_flash_regs
the C2CR register don't contain LOCK and OPTLOCK bits, and this explain
the addition of new register index called STM32_FLASH_CR_WLK_INDEX to
look-up the CR with lock, to be used in locking/unlocking the flash.
note: DBGMCU_IDCODE cannot be read using CPU1 (Cortex-M0+) at AP1,
to solve this read the UID64 (IEEE 64-bit unique device ID register)
