Tomas Vanek 1ce51507a1 target: rewrite jim_target_event_list to handle_target_event_list
jim_target_event_list handler used command_print() in jim handler.

Rewriting the jim handler to the OpenOCD command is easy
as get_current_target() returns proper target for prefixed commands since

Antonio Borneo f9986394dc target/cortex_a: use extensively cortex_a_wait_dscr_bits()
We have the function to wait for bits in dscr. Use it whenever
possible.

When the bit to test is DSCR_INSTR_COMP, use instead the wrapper
function cortex_a_wait_instrcmpl().

Antonio Borneo d870ecf5ff target/cortex_a: check dscr before timeout
In function cortex_a_wait_dscr_bits() the last read on dscr gets
ignored in case of timeout, even if it finally provides the value
that would trigger a successful return.

Check the returned value before testing the timeout.
Also, print a message on failure reading dscr.

Antonio Borneo d3a9e535d5 target/cortex_a: fix waiting for target halted after step
Depending on adapter speed, the function cortex_a_poll() can take
time to execute and can complete successfully when the timeout is
already expired. Checking the timeout at function return causes a
timeout error while that could be avoided.

Check the target status at cortex_a_poll() return, before checking
for the timeout.

The code for this command is currently replicated in cortex_a and
in mips_m4k and is going to be added again for cortex_m.
Plus, it is going to be obsoleted by the HW thread pseudo RTOS.

Consolidate in smp.c a single instance of the command. This will
simplify both obsoleting it and adding it to cortex_m, whatever
change comes first.

Antonio Borneo 246782229f smp: replace commands smp_on/smp_off with "smp [on|off]"
Seams over-engineered having two separate commands to turn SMP
on/off. Plus it is missing the possibility to dump the current
status of SMP and would be weird adding an additional command
for it. Moreover, such commands are replicated in few targets so
it would make sense centralizing them.

- Deprecate the commands "smp_on" and "smp_off".
- Add a new command "smp" that accepts optional parameters
  "[on|off]" and prints the SMP status when run without
  parameters. This replaces the two commands above.
- Put the deprecated and the new command handlers in smp.c
- Update the documentation, except for mips_m4k, since it is not
  available yet.
- Promote the macro foreach_smp_target to global context and use
  it where possible.

Tomas Vanek fd8a3c9516 target, breakpoints: improve error handling
handle_bp_command_set() showed the error message
"Failure setting breakpoint, the same address(IVA) is already used"
on any error returned from (xxx_)breakpoint_add().
Paradoxically breakpoint_add() returned ERROR_OK if it detected
duplicated bp address.
context_breakpoint_add() and hybrid_breakpoint_add() returned -1
instead of OpenOCD compatible error if they detected duplicity.

Introduce ERROR_TARGET_DUPLICATE_BREAKPOINT
Unify error handling to LOG_ERROR() any error in (xxx_)breakpoint_add()
Remove misleading error messages from handle_bp_command_set()
handle_bp_command_set() returns error if the target does not implement
add_context_breakpoint or add_hybrid_breakpoint.

Antonio Borneo 7a80a74e81 arm_adi_v5: rewrite dap_to_jtag and dap_to_swd
The functions dap_to_jtag() and dap_to_swd() have been introduced by
3ef9beb52c ("ADIv5 DAP ops switching to JTAG or SWD modes") in
arm_adi_v5.c by using the JTAG queue only.
Later, in 6f8b8593d6 ("ADIv5 transport support moves to separate
files") the functions has been moved in adi_v5_swd.c and adi_v5_jtag.c
but keeping the dependency from JTAG queue.
The functions does not work if the current transport is not JTAG.

Move back the functions in arm_adi_v5.c, replace the input parameter
"target" with "dap", use the transport to detect if the JTAG queue is
present, in case of SWD transport use the proper method, for other
transports report error.
Reuse the ADI v5 sequences already present in jtag/swd.h.
Also, OpenOCD does not support switching to another transport after
the initial selection, so do not change DAP's ops vector.

Cody P Schafer 49bd64347a armv7m: always set xPSR.T=1 when starting an algorithm
xPSR.T sets the processor to Thumb mode when set to 1. ARMv7-M only
supports execution of Thumb instructions, so it must always be set to 1.

If xPSR.T is set to 0 on armv7m, a usage fault is generated when a
instruction execution is attempted.

On armv7m, issuing a reset causes the vector table to be examined. PC
and xPSR.T  are loaded from the vector table at byte offset 4. xPSR.T is
taken from the least significant bit this value, PC from the remaining
bits.  This occurs even with `reset halt`, as the reset itself causes
this load to occur without the execution of any instructions.

As a result of this, following a reset with a "bad" value programmed in
the vector table, openocd would be unable to run algorithms on the
target, as running them would immediately result in a usage fault due to
xPSR.T being unset (0).

Allow algorithms to run regardless of the content of the vector table by
explicitly setting xPSR so that xPSR.T=1 prior to executing an
algorithm. One can think of this as openocd more closely emulating a
reset or branch instruction in executing it's algorithms.

Antonio Borneo bff87a7f28 target/cortex_a: enable DSCR_HALT_DBG_MODE during examine
Arm architecture reference manual DDI0406C reports at page 2024 in
table C3-1 the processor behaviour on debug events depending on
the debug-mode (none, monitor or halt), mode selected through the
bits MDBGen and HDBGen in DSCR register.

The halt request is served independently from the debug-mode. Thus
it's useless to enable the halt debug-mode in cortex_a_halt() by
setting the bit HDBGen (macro DSCR_HALT_DBG_MODE).

On the other side, halting for a breakpoint, a watchpoint or a
vector catch requires being in halt debug-mode.
Today HDBGen is set only in cortex_a_halt(), so we are forced to
halt the core at least once before it can be halted for hitting a
breakpoint/watchpoint/vector-catch. This is annoying since there
is no need to halt the target to set a HW breakpoint.

Move in cortex_a_init_debug_access() the selection of the halt
debug-mode, so the mode is set during examine.
To prevent a misconfigured hardware breakpoint/watchpoint/vector
catch to halt the target when OpenOCD has already quit, return to
debug-mode none at OpenOCD exit.

sophisticated model for tracing, however the setup and usage is similar.
This patch also cleans up the command interfaces of the other esirisc
command groups and adds additional debugging information to log messages
when dealing with CSRs.

This patch "finalizes" support for 32-bit eSi-RISC targets.

Antonio Borneo 8b66c96974 armv7a_mmu: s/LOG_ERROR/LOG_WARNING/ on address translation failure
When GDB analyses the status of the target it try to guess the
current stack frame and issues few memory read.
E.g. on ARM targets GDB uses R11 value as a potential frame-pointer
and reads at the address pointed by R11.
The address of such memory read is not always valid and can trigger
an address translation failure.

Replace LOG_ERROR with LOG_WARNING in case the virtual address does
not have a hit in TTB; print the virtual address in the warning
message and discriminate the two identical messages with [1]/[2].

Christopher Head ea41048830 Permit null target on TCL connection
In previous versions of OpenOCD, it was possible to connect to the TCL
RPC interface without a current target. In `tcl_new_connection`, the
curent target would be queried by number, and the possibility of a null
current target was handled properly.

In commit bb9d9c6026, the
`get_target_by_num` call was replaced by a `get_current_target` call,
without noticing that `get_current_target` aborts if there is no current
target, whereas `tcl_new_connection` is perfectly able to handle that
situation.

Provide a `get_current_target_or_null` function for use by consumers who
are OK with a null current target, and use it in `tcl_new_connection`.

Antonio Borneo fac9be64d9 target/cortex_a: remove buggy memory AP accesses
The armv7m debug port provides a direct access to the CPU memory
bus, allowing the debugger to bypass the CPU for every memory
operation.
The armv7a debug port doesn't offer the same feature, mainly
because CPU caches and MMU makes the direct memory access more
tricky. Nevertheless most SoC with armv7a provide direct memory
access through an AHB bus available on another DAP access port,
different from the debug port.

The original port of cortex_a in OpenOCD was inspired from the
working cortex_m code, and provided optional memory access
through the AHB, if present.
The code for AHB access is problematic and partially buggy due
to incomplete management of cache coherency and missing check of
page boundary during virtual address operations.

With the commit 5d458cf727
("target/mem_ap: generic mem-ap target") we have a clean support
for memory access through system buses connected to DAP AP, which
obsoletes the buggy memory AP hack in cortex_a.

Remove any code that uses the memory AP accesses in cortex_a.

Antonio Borneo 1e3ba2046c arm_adi_v5: do not deactivate power domains while trying to clear sticky error
At OpenOCD start-up the operation of clearing the sticky error in
CTRL/STAT register ignores the current value of the power domains
bits CDBGPWRUPREQ and CSYSPWRUPREQ in the same register and
incorrectly set them to zero.
This abrupt disable does not follow the requirement in IHI0031 to
wait for the acknowledgment of power disabled before continuing.
The power domains are then re-enabled immediately after; it is
possible that such short disable period has passed undetected or
has been tested only on devices that do not implement the power
domains.
Anyway, this sequence is incorrect and can generate unexpected
and hard-to-debug issues while OpenOCD attaches to a running
target that implements power domains.

Anticipate the initialization of dap->dp_ctrl_stat and use it
while clearing the sticky bit. This has the additional effect of
avoiding a power disable in the error recovery part of the
function dap_dp_read_atomic().
Keep the same sequence of read/write in dap_dp_init() to avoid
breaking the initialization of some problematic target.
Add comments to document these choices.

Commit c8926d1457 introduces the
context and hybrid breakpoint types beside existing SW and HW
types. The new field "asid" is non-zero only for these new types.

The commit above did not properly initialize "asid" to 0 for a
temporarily HW breakpoint used during single step. This causes
cortex_a_unset_breakpoint() to identify this breakpoint as of
type "hybrid".

Identified through valgrind error:
Conditional jump or move depends on uninitialised value(s)
Actually valgrind triggers a total of 10 messages about use of
uninitialized variables, but they are all caused by the first
conditional jump bases on "asid != 0".

Fixed by initializing "asid" to 0 in cortex_a_step().

The condition to force the update of CSW cache is incorrect and it will

Antonio Borneo 56cdc3f3d5 target/cortex_a: poll all targets in SMP node after halt
The periodic poll scans all the targets in the same order they
have been declared in the configuration file.
When one target in a SMP node halts, the transition is detected
in the following poll and this triggers a halt request to all the
other cores of the SMP node.
The targets that will be polled afterwards will be identified as
"halted", but the targets already scanned will remain as
"running" until the next periodic poll.
This creates a race condition with GDB; GDB sets the breakpoints
when runs the target and removes them as soon as the target is
halted. When it receives the halt event, it starts removing the
breakpoints and fails on the targets that are still reported as
"running".

Fixed by polling all the targets in the SMP node before informing
GDB about the halt event.
This implementation is almost copy/paste from the one in aarch64.

If the argument is not a numeric value (e.g. "pipe", "disabled", ...)

Add the option "-gdb-port number" to the commands "target create" and
"$target_name configure" to override, for the specific target, the
general global configuration.

This permits to use a per target "-gdb-port disabled", when no gdb
port is required for that specific target.

Antonio Borneo e48690cb26 target/arm_adi_v5: allow commands apsel and apcsw during init phase
The current implementation of apsel cannot be executed during the
initialization phase because it queries the DAP AP to retrieve and
print the content of IDR register, and the query is only possible
later on during the exec phase.
But IDR information is already printed by the dedicated command
apid, making redundant printing it by apsel too.
Being unable to run apsel during initialization, makes also apcsw
command (that depends on apsel) not usable in such phase.

Modify the command apsel to only set the current AP, without making
any transfer to the (possibly not initialized yet) DAP. When run
without parameters, just print the current AP number.
Change mode to COMMAND_ANY to apsel and to apcsw.

Antonio Borneo 9363705820 arm_adi_v5: put SWJ-DP back to JTAG mode at exit
When SWD mode is used, current OpenOCD code left the SWJ-DP in
SWD mode at exit. Also, current code is unable to switch back the
SWJ-DP in JTAG at next run, thus a power cycle of both target and
interface is required in order to run OpenOCD in JTAG mode again.

Put the SWJ-DP back to JTAG mode before exit from OpenOCD.

Use switch_seq(SWD_TO_JTAG) instead of dap_to_jtag(), because the
latter is not implemented on some interfaces. This is aligned
with the use of switch_seq(JTAG_TO_SWD) in swd_connect().

Antonio Borneo 42097baf19 armv7a: read ttbcr and ttb0/1 at every entry in debug state
Commit bfc5c764df avoids reading
ttbcr and ttb0/1 at every virt2phys translation by caching them,
and it updates the cached values in armv7a_arch_state().
But the purpose of any (*arch_state)() method, thus including
armv7a_arch_state(), is to only print out and inform the user
about some architecture specific status.
Moreover, to reduce the verbosity during a GDB session, the
method (*arch_state)() is not executed anymore at debug state
entry (check use of target->verbose_halt_msg in src/openocd.c),
thus the state of translation table gets out-of-sync triggering
	Error: Address translation failure
or even using a wrong address in the memory R/W operation.

In addition, the commit above breaks the case of armv7r by
calling armv7a_read_ttbcr() unconditionally.

Fixed by moving in cortex_a_post_debug_entry() the call to
armv7a_read_ttbcr() on armv7a case only.
Remove the call to armv7a_read_ttbcr() in armv7a_identify_cache()
since it is (conditionally) called only in the same procedure
cortex_a_post_debug_entry().

Fixes: bfc5c764df ("armv7a: cache ttbcr and ttb0/1 on debug
state entry")
