The function in question does not need to change target state. It is a
target-type-dependant function, however, IMHO, it is safe to assume that
any target type would not need to change type-independant state of a
target to figure out the arch.

There are quite a lot of "getters" in target interface.
They do not change target structure, nevertheless the structure is
passed to these functions via a plain pointer.
The intention is to clarify the purpouse of these functions by passing

clang build triggers an error for an uninitialized value of the

This is a false positive, as the macro
#define MIPS32_CONFIG3_ISA_MASK (3 << MIPS32_CONFIG3_ISA_SHIFT)

Commit e370e06b72 ("target: Deprecate 'array2mem' and
'mem2array''") has already replaced the deprecated root versions
of commands mem2array and array2mem with TCL proc's that use
'read_memory' and 'write_memory'. It has left the deprecated code
of the target's version of the commands because the effort to code
the TCL replacement was not considered valuable.
To drop the last jim_handler commands, I consider much easier and
less error-prone to code them in TCL instead of converting the
deprecated code to COMMAND_HANDLER.
Drop the code in target.c and extend the TCL proc's.
While there, add the TCL procs to _telnet_autocomplete_skip.

When requested by the core code (handle_breakpoints = true),
arc_resume() should be able to advance over a potential breakpoint set
at the resume address instead of getting stuck in one place. This is
achieved by removing the breakpoint, executing one instruction,
resetting the breakpoint, then proceeding forward as normal.
With this patch applied, openocd is now able to resume from a
breakpoint halt when debugging ARCv2 targets via telnet.
This has previously been committed to the Zephyr project's openocd repo

The original code supported ADIv5 only, just one SELECT register
with some reserved bits - the pseudo value DP_SELECT_INVALID was
just fine to indicate the DP SELECT register is in an unknown state.
Added ADIv6 support required DP SELECT and SELECT1 registers
without reserved bits. Therefore DP_SELECT_INVALID value became
reachable as a (fortunately not really used) ADIv6 AP ADDR.
JTAG DPBANKSEL setting support introduced with ADIv6 does not
honor DP_SELECT_INVALID correctly: required select value
gets compared to DP_SELECT_INVALID value and the most common zero
bank does not trigger DP SELECT write.
DP banked registers need just to set DP SELECT. ADIv6 AP register
addressing scheme may use both DP SELECT and SELECT1. This further
complicates using a single invalid value.
Moreover the difference how the SWD line reset influences
DPBANKSEL field between ADIv5 and ADIv6 deserves better handling
than setting select cache to zero and then to DP_SELECT_INVALID
in a very specific code positions.
Introduce bool flags indicating the validity of each SELECT
register and one SWD specific for DPBANKSEL field.
Use the latter to prevent selecting DP BANK before taking
the connection out of reset by reading DPIDR.
Treat DP SELECT and SELECT1 individually in ADIv6 64-bit mode.
Update comments to reflect the difference between ADIv5 and ADIv6
in SWD line reset.

SRL -- Shift right logical
Encoding: 0000 00-- ---t tttt dddd dhhh hh00 0010
This corrects the opcode constant for SRL and adds the SRA opcode for
completeness.
There is only one user of MIPS32_OP_SRL in src/flash/nor/cfi.c:
Since the mask constant (0x00000080 for the DQ7 mask) shifted in this
case would never have the sign bit set, it worked fine even though it
was accidentally using the SRA opcode instead of SRL.
