The command 'vdebug mem_path' is reported in the documentation as
'{Config Command}', but the code sets mode = COMMAND_ANY.
The code of the commands sets some value that is only used during
the init phase, so the documentation is correct.

When target is stopped in WFI/WFE or is in an infinite loop, the
sampled PC will always return the same value.
Command 'profile' requires that distance between min and max PC
should be at least 2, which is not the case for constant PC, and
incorrectly enforces the check through as assert().
Move the code that reads the optional parameters 'start' and 'end'
and check the gap 'end - start' before running the profile.
For self-computed min and max, increase max (or decrease min) to
match the required constraint.
Drop the assert().

The implementation of command 'monitor profile' has few
issues:
- the address_space is a signed int, so cannot wrap-around on
space over INT_MAX;
- max address is incremented without check for overflow;
- assert() used on errors instead of returning error codes;
- only handles 32 bits PC;
- output file created and left empty on error.
This patch fixes the first two issues, as a wider fix would be too
invasive and should be postponed in a following series.

Clang complains about the variable 'orig_dfsr' that can be used
uninitialized both in cortex_a_read_cpu_memory() and in
cortex_a_write_cpu_memory().
The issue is caused by an incorrect error path that used to jump
through 'goto out'. The code after the label 'out' is specific to
handle the case of an error during memory R/W; it is incorrect to
jump there to handle an error during the initialization that
precedes the memory R/W.
Replace the 'goto out' with 'return retval'.
Remove the label 'out' that is now unused.

Commit 35a503b08d ("arm_adi_v5: add ap refcount and add get/put
around ap use") modifies the examine functions of mem_ap, cortex_m,
cortex_a and aarch64 by calling dap_put_ap() and then looking again
for the mem-ap and calling dap_get_ap().
This causes an issue if the system is irresponsive and the examine
fails and left the AP pointer to NULL. If the system was already
examined the NULL pointer will cause a SIGSEGV.
Commit b6dad912b8 ("target/cortex_m: prevent segmentation fault
in cortex_m_poll()") proposes a fix for one specific case and only
on cortex_m.
Modify all the examine functions by skipping look-up for the AP if
it was already set in a previous examine; the target's AP is not
supposed to change during runtime.

Indicate to the JTAG driver that it does not need
to read and return the DR register value after scanning the
JTAG chain.
riscv_batch_run(), calls jtag_add_dr_scan() to schedule a
DR scan operation. Eventually, this will result in the JTAG
driver performing a JTAG scan to write to or read from DR.
The decision on whether to write to and/or read from DR
register is determined by the second parameter to
jtag_add_dr_scan(), i.e. a "struct scan_field".
Of particular interest here is if
batch->fields[i]->in_value is not NULL, the JTAG developer
must return the DR value collected from the JTAG scan
operation.
When creating the DR scan operation instruction with
riscv_batch_add_dmi_write(), batch->fields[i]->in_value points
to a location in batch->data_in buffer,
meaning batch->field[i]->in_value is not NULL, and the JTAG
developer must therefore read and return the DR value collected.
The returning of the DR value is redundant in a write
operation.
This patch set batch->fields[i]->in_value to NULL to indicate
the DR value need not be returned. This allows the JTAG
developer to optimize away any code associated with returning
the DR value.
Normally, the extra work to return the DR value is negligible.
However, in one usecase it introduces significant delays
In this use case a JTAG driver forwards
all JTAG scan to a server on a network. If the server has to
return the DR value, it has to perform the JTAG scan before
replying to the JTAG driver, and only then the JTAG driver
can send the next JTAG scan operation. However, if there is
no need to return the DR value, the server can
acknowledge the JTAG operation request immediately,thus
signalling to the JTAG driver that it is free to send the next
JTAG scan operation. At the same time of receiving the second
JTAG operation the server will process the original JTAG scan.
This saves time and mitigates network delay. Also, not having
to include the DR value in resulting in smaller reply packet
from server to JTAG driver and save on network traffic.
This doubles download speeds to spike using remote bitbang.

`xtensa_do_step` is invoked from `xtensa_prepare_resume` to silently
step over BP/WP before resuming.
For example; in the case of WPs (DEBUGCAUSE_DB), in the current
implementation `xtensa_do_step` will generate one more
`TARGET_EVENT_HALTED` after the original one caused by WP itself.
This patch moves the halted event cb call after
the step is done successfully.

This GPIO driver is common to SoCs that have in-order ARM cores
(BCM2835) as well as superscalar (BCM2836-7) and speculative
out-of-order cores (BCM2711).
For BCM2837 and BCM2711, the processor can dual-issue stores and
is free to merge writes to peripheral memory for pages mapped
MT_NORMAL_NC, which is the default provided by /dev/[gpio]mem.
This can cause glitches (or missing edges) on GPIO pins when
toggled with no delay, as pipelined writes to the same address
can get arbitrarily squelched.
To prevent this happening, make sure the preceding write ops are
flushed outside the shareable domain by using a memory barrier.

* [riscv] step operation handler should respect handle_breakpoints parameter
When step operation is requested the OpenOCD frontend (like gdb server
or TCL server) has an option to control how existing breakpoints are
handled upon step.
Some OpenOCD frontends (like gdbserver) may choose to disable special
handling of existing breakpoints - thus handle_breakpoints is set to 0,
while others (like TCL server) expect target handler to temporary
disable the matching breakpoint to allow the step operation to complete
successfully.
In the current implementation handle_breakpoints parameter was ignored
by target-specific handler. Thus, the following sequence of commands:
```
halt
bp <current_pc> 4
step
```
Resulted in *step* operation to not change PC because of bp match.
This commit addresses this issue.

usually an issue, in the case of the at91samd flash driver, the 16-bit
'command' register must have both halves written in the same
operation.
Fortunately, this register has two pad bytes above it in the address
space, making it safe to always access with 32-bit operations.

we already have a target associated with each operation, and from there
we can find the desired hart id. dm013_info_t already tracks
current_hartid (meaning which hart ID is currently selected by the DM).
This makes the code simpler to understand. Also it turns out we don't
need to make sure the correct hart ID is currently selected because
there are only a few real entry points.

dsp563xx.c:2143 Result of 'calloc' is converted to a pointer

It's a false positive because calloc() is properly used in this

Either

When FreeRTOS (at least) is compiled with -flto, this leaves certain
static symbols with .lto_priv.0 appended to their name. Arguably this
could be considered to be a gdb or gcc bug, but one place to resolve it
for OpenOCD usage is here at symbol lookup time.
Note that the ".0" is for the first such instance of the variable as a
static; additional ones would end up as ".1", ".2", etc, and are not
considered here.

Commit c7eaaf6204 ("openocd: prepare for jimtcl 0.81 'expr'
syntax change") replaces the jimtcl command "expr" with an openocd
version that detects the TCL syntax change and prints a warning.
The openocd "expr" command will be dropped after v0.12.0,
One side effect is that openocd invokes polling the target after
every openocd command, causing scripts that use several "expr"
commands to run much slower; see [1].
The proper fix would require openocd to invoke polling only at the
time period deadline, instead of at each command. Such fix is too
risky to be applied now, due to short time before v0.12.0-rc1.
As a temporarily workaround, let openocd to detect the "expr"
command and skip the polling.
This will be dropped together with the openocd "expr" command.
