Update mips32 instructions, add barrier and sync related insts.
Add SYNC and barrier instruction blocks for memory access safety.

These instructions are not supported on Lexra and/or MIPSr1 CPUs,
detections were added and they will be executed conditionally.

Rework mips32_pracc_read/write_regs function.

Tomas Vanek 357996d996 target/adi_v5_swd: optimize sequences in swd_connect_multidrop()
swd_connect_multidrop() sent DORMANT_TO_SWD and called
swd_multidrop_select_inner(). DORMANT_TO_SWD sequence ends
with a LINE_RESET sequence.
swd_multidrop_select_inner() sent LINE_RESET sequence again.
It was useless in this case.

swd_connect_multidrop() emited JTAG_TO_DORMANT and DORMANT_TO_SWD
sequences before connecting each DAP in SWD multidrop bus.
It is sufficient to emit JTAG_TO_DORMANT and DORMANT_TO_SWD
just once and emit the shorter LINE_RESET instead for subsequent DAPs.

Introduce a global variable swd_multidrop_in_swd_state
and use it to control what sequence is emitted.

In case of reconnect after an error, always use the full switch
JTAG_TO_DORMANT and DORMANT_TO_SWD.

Tomas Vanek ee3fb5a0ea target/arm_adi_v5: fix DP SELECT logic
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.

Tobias Diedrich 62b526dbbd mips32: MIPS32_OP_SRL was using SRA opcode.
The mips opcode macro for the SRL opcode was using the wrong constant
value:

SRA -- Shift right arithmetic
Encoding: 0000 00-- ---t tttt dddd dhhh hh00 0011

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.

way_shift be set to the arbitrary value of 0 because in the case where

Artemiy Volkov d20304b3fb target/arc: do not invalidate icache when (un)setting breakpoints
Currently, instruction cache is being invalidated in
arc_{un,}set_breakpoint() regardless of whether the breakpoint's type is
HW or SW. For SW breakpoints, this has no net effect as the caches are
flushed as a by-product of overwriting instructions in main memory and
is thus merely unnecessary; but for HW breakpoints this invalidation is
not preceded by a flush and might lead to loss of data. This patch
removes the invalidate() call altogether to correct this undesired
behavior for HW breakpoints.

With this patch applied, all supported HW breakpoint tests from the gdb
testsuite are now passing with the arc-openocd backend.

Antonio Borneo bdf73617e7 armv8_dpm: fix registers read at debug entry
The comment above armv8_dpm_read_current_registers() doesn't match
the implementation, as the function reads all the registers from
ARMV8_PC and above.
The registers currently read are not relevant to answer to the
usual GDB initial request through the 'g' packet. Plus the lack of
differentiation per core state (AArch32 vs AArch64) causes the
read of not existing registers in AArch32 triggering errors, as
tentatively fixed by https://review.openocd.org/5517/

Fix the code to read the registers initially required by GDB.
Modify the comment to report the register list in AArch32 and in
AArch64.
Keep the extra checks inside the read loop, even if they are
mostly irrelevant; this could prevent errors if someone needs to
extend the number of registers to read.

The current implementation of the register's description in
OpenOCD does not allow to discriminate among AArch32 and AArch64
registers. Add a TODO comment to highlight it.

This reverts commit 047b1a8fc2.

Commit 047b1a8fc2 ("target/image: zero-initialize ELF segments
up to p_memsz") breaks the backward compatibility introducing some
problem:
- an empty bss segment with paddr in SRAM gets zero filled at load
  but does not survive after a reset, causing verify to fail;
- an empty bss segment with paddr in FLASH causes excessive flash
  usage, which can exceed flash size (causing error) and makes
  flash aging faster.

Revert it while looking for a better implementation.

Antonio Borneo 8670ad4caa target/espressif: fix clang report on list use
It looks like a false positive.
Scan-build considers as possible to:
- have list_empty() return false;
- list_for_each_safe() to not execute any loop, thus not assigning
  a non-NULL value to 'block';
- the NULL pointer 'block' is passed to list_del().
This is not possible because with list_empty(), the loop runs at
least once.

Rewrite the function to simplify the code and making it easier for
scan-build to check it.

This also drops an incorrect use of list_for_each_safe(), where
the 'safe' version was not required.

Marian Buschsieweke 6e67f1473a helper: Add generic little endian CRC32 function
This generalizes the little endian CRC32 function used in the OR1K
target and moves it to a common helper, so that other places do not need
to reinvent the wheel. It is directly used in the OR1K target.

letters.[1] Not adhering to the definition can cause issues with tools
interacting with the GDB which expect the correct casing.

Tomas Vanek 59763653c6 target/cortex_m: add SMP support for Cortex-M
Cortex-M support for SMP multicore targets.

This SMP implementation unlike older ones does not act
on the first halted target found. It polls targets
until a SMP group is finished and stores eventual
'halted' events instead of emitting them. As soon as polling
of a group is done, poll proceeds with SMP related tasks.
This approach improves detection of a reason why debug
stopped - a correct reason is detected for all targets,
not only for the first found.
Drawback: SMP target group should be defined in the same
order as the targets were defined.

Obsolete gdb 'J' packet/smp_gdb command core switching is not implemented,
use with rtos hwthread.

Only one core is resumed if debug_execution is requested.

Some ideas taken from Graham Sanderson's [4936]
and src/target/aarch64.c

Added error checking of armv7m_restore_context().

Koudai Iwahori d0436b0cda armv8: Add support of pointer authentication
When pointer authentication is enabled, some upper bits of the link
register (LR[63:VA_SIZE]) are used to store a signature. Therefore, GDB
need to remove the signature to get backtraces.
GDB has support of pointer authentication. When pointer authenticaion is
enabled, GDB requests 8-bytes mask to the target to remove the
signature. mask[63:VA_SIZE] should be all set and mask[VA_SIZE-1:0]
should be all cleared. GDB removes the signature by addr&~mask or
addr|mask.
I added a feature to provide the mask for pointer authentication.
