Tomas Vanek 23c33e1d3a target/cortex_m: workaround Cortex-M7 erratum 3092511
When an asynchronous exception occurs at the same time
as a breakpoint event (either hardware breakpoint or software breakpoint),
it is possible for the processor to halt at the beginning of the
exception handler instead of the instruction address pointed
by the breakpoint.

During debug entry in exception handler state and with BKPT bit set
as the only break reason in DFSR, check if there is a breakpoint, which
have triggered the debug halt. If there is no such breakpoint,
resume execution. The processor services the interrupt and
halts again at the correct breakpoint address.

The workaround is not needed during target algo run (debug_execution)
because interrupts are disabled in PRIMASK register.

Also after single step the workaround resume never takes place:
the situation is treated as error.

Commit f9509c92db ("itm: rework itm commands before 'init'")

no 'itm port[s]' is issued.

Call armv7m_trace_itm_config() unconditionally to handle it.

The command 'gdb_report_register_access_error' is used to silence
errors while reading registers and not reporting them to GDB.
Nevertheless, the error is printed by a LOG_ERROR() in armv8_dpm.

Change the message to LOG_DEBUG().
It will still cause the error to be propagated and eventually
printed by the caller (e.g. by the command 'reg').

Tomas Vanek 4892e32294 target/cortex_m: allow poll quickly get out of TARGET_RESET state
cortex_m_poll_one() detects reset testing S_RESET_ST sticky bit.
If the signal comes unexpectedly, poll must return TARGET_RESET state.

On the contrary in case of polling inside of an OpenOCD reset command,
TARGET_RESET has been has already been set and we need to get out of
it as quickly as possible.

The original code needs 2 polls: the first clears S_RESET_ST
and keeps TARGET_RESET state, the current TARGET_RUNNING or TARGET_HALTED
is reflected as late as the second poll is done.

Change the logic to keep in TARGET_RESET only when necessary.

operations like:
- assert adapter's srst;
- write some register to catch the reset vector;
- invalidate the register cache.

Targets created with -defer-examine gets the examine flag reset
right before entering in their assert_reset(), disrupting the
actions above.

For targets created with -defer-examine, move the reset examine
after the assert_reset().

always started, even if necessary device configuration fails. This
behaviour is confusing to users. Also, the TPIU must be disabled before
re-configuration is possible.

Start capturing and enable TPIU only if no errors in pre/post-enable
events occurred.

Historically, the function cortex_a_dap_write_memap_register_u32()

Antonio Borneo caabdd4a66 cortex_a: drop the command 'cache auto'
The command 'cache auto' was introduced with commit cd440bd32a
("add armv7a_cache handlers") in 2015 to allow disabling the cache
handling done automatically by OpenOCD.
This was probably a way to test the cache handling when there were
still the two independent accesses for APB-AP CPU debug and for
AHB-AP memory bus.

The handling of cache for cortex_a is robust and there is no more
reason to disable it.
The command 'cache auto' is not used in any upstream script.
On target aarch64 this command has never been introduced as the
cache is always handled automatically by OpenOCD.

Drop the command 'cache auto' and add it in the deprecated list.
Drop the flag 'auto_cache_enabled' by considering it as true.
Rename the function 'armv7a_cache_auto_flush_all_data()' as
'armv7a_cache_flush_all_data()' and, while there, fix the error
propagation in SMP case.

Antonio Borneo dbef02789f cortex_a: drop useless cache invalidate on mem write
The initial OpenOCD code for Cortex-A (ARMv7a) [1] was merged in
2009 but, due to lack of public documentation for ARMv7a, it was
almost a simple copy/paste from the existing code for Cortex-M
(ARMv7m).

On Cortex-M the same AP provides access to both CPU debug and CPU
memory. This feature is not present on ARMv7a.
To still keep some communality with ARMv7m code, the change [2]
splits the CPU debug access from the CPU memory access by using
two independent AP; this is copied from the system architecture of
TI OMAP3530 which provides to DAP a direct AHB-AP memory bus on
AP#0, separated from AP#1 for the APB-AP CPU debug.
But the direct memory access through the system bus breaks the
coherency between memory and CPU caches, so change [3] added some
cache invalidation to avoid issues.

The code to allow ARMv7a CPU to really read/write in CPU memory
was added by change [4] in 2011. Such still not optimized
implementation was very slow, so it did not replace the access
through the system bus. A selection through DAP's 'apsel" command
was used to select between the two modes.

Only in 2015, with change [5], the speed of CPU read/write was
improved using the DCC_FAST_MODE. But the direct access to the
memory through the system bus remained.

Finally, with change [6] in 2018 the system bus access was dropped
for good, as the new virtual target "mem_ap" could implement such
access in a more clean way.
Only memory access through CPU remained for ARMv7a.
Nevertheless, a useless cache invalidation remained in the code,
decreasing the speed of the write access.

Drop the useless cache invalidate on CPU memory write and the
associated comment, not anymore valid.
Drop the now unused function armv7a_cache_auto_flush_on_write().

This provides a speedup of between 4 and 8, depending on adapter
and JTAG/SWD speed.

Tomas Vanek 4c0a2cf42e target/adi_v5_swd: fix DP registers banking
ADIv6 brought more complicated rules for DP reg 0 banking.
Neither the original implementation [1] nor the later
modification [2] respected that the DP reg 0 is banked
for read only, not for write. Enforcing of an useless
SELECT write before a write to ABORT register may trigger
FAULT (CTRL/STAT bits ORUNDETECT and STICKYORUN are set)
or WAIT (DP is stalled by an outstanding previous operation)
and therefore make ABORT register virtually unusable
on some adapters (bitbang, CMSIS-DAP).

There are DP ABORT specific functions swd_queue_ap_abort()
and swd_clear_sticky_errors() which worked around the problem
using the lowest level swd->write_reg(). Using a specific
write procedure for a single DP register was error prone
(there are other DP_ABORT writes using swd_queue_dp_write_inner())
and also the Tcl command 'xx.dap dpreg 0 value' suffered
from unwanted SELECT write.

Other smaller discords in DP banking probably do not
influence normal DP operation however they may complicate
debugging in corner cases.

Adhere strictly to the DP banking rules for both ADI versions.

In 2008 the commit 1829361253 ("define resetting
the target into the halted or running state as an atomic operation.")
introduced the target_halt() call to the end of cortex_m3_assert_reset(),

Checkpatch-ignore: GIT_COMMIT_ID

A year later the commit ed36a8d15d
("... Updated halt handling for cortex_m3")
prevented cortex_m3_halt() take any action in case of TARGET_RESET state.
This narrowed the target_halt() called from cortex_m3_assert_reset()
to setting target->halt_issued and storing a time stamp.

Introducing ocd_process_reset(_inner) made the setting of halt_issued
and halt_issued_time useless. The Tcl function waits for halt
of all targets if applicable.

cortex_m_halt() and also target_halt() does not work as expected
if the cached target state is TARGET_RESET (although the core could
be out of reset and ready to be halted, just have not been polled).
Explicit Tcl arp_poll must be issued in many scenarios.

Remove the useless hack.

Also remove the explicit error return from cortex_m_halt_one()
in case of RESET_SRST_PULLS_TRST and asserted srst. If the communication
with the target is gated by any reset, cortex_m_write_debug_halt_mask()
fails. Propagate the error return of this call instead.

Evgeniy Naydanov 67675323e1 target: pass target to observers via const pointer
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
the `target` structure as a pointer to constant data.

Antonio Borneo 6e6d486de2 target: drop deprecated code for mem2array and array2mem
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.

Evgeniy Didin 0de852f561 target/arc: skip over breakpoints in arc_resume()
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
(see https://github.com/zephyrproject-rtos/openocd/pull/31).

It was useless in this case.

swd_connect_multidrop() emited JTAG_TO_DORMANT and DORMANT_TO_SWD

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

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.

Erhan Kurubas d3ffcc784d target/espressif: add algorithm support to execute code on target
This functionality can be useful for;
1-ESP flashing code to load flasher stub on target and
write/read/erase flash.
2-ESP GCOV command uses some of these functions to run
onboard routines to dump coverage info.

This is high level api for the Espressif xtensa and riscv targets

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.

We were previously inadvertently clearing the top 32 bits of SCTLR_EL1
during read_memory/write_memory as a result of using 32-bit operations
to access the register and because the fields used to temporarily
store the register were 32-bit. Fix it.

Peter Collingbourne ee96a95d44 openocd: src/target: Correctly handle CCSIDR_EL1.Associativity=0
Associativity=0 means that only one CMO is needed for all ways.
It could also mean that the cache is 1-way, but this is less likely.

Currently Associativity=0 causes us to hang in the while loop in
decode_cache_reg. Fix it by skipping the loop in this case. We can let
way_shift be set to the arbitrary value of 0 because in the case where
Associativity=0 we only ever shift 0 by it before ORing it into the
CMO operand.
