OpenOCD currently uses improper "fence" instruction:
"FENCE" opcode with empty predecessor and successor sets.
Such instruction has no effect and is reserved for future use
as a HINT instruction (RISC-V Unprivileged ISA spec V20191213,
section 2.9).
This patch fixes it by using the proper "fence rw,rw"
instruction.

This command is supposed to be a start at a compliance test for system
bus access. It doesn't pass against spike because it doesn't handle all
cases where the interface might be busy. It's not documented. As far as
I know nobody uses it.
So delete 400 lines of code instead of trying to fix it.

This lets the user set an itrigger trigger, which doesn't fit in the
normal breakpoint abstraction.
This implementation only allows control of a single itrigger. Hardware
could support more than one, and that may be useful to catch different
interrupts in different execution modes. But it would make the code/UI
more complex and it feels like an unlikely use case.

It used to set all states to halted, but that's not right for harts that
are now unavailable. (It might be possible to call poll() at the right
time instead of duplicating some of its code, but I didn't see an easy
way to do that. The real requirement is that target->state is set to
TARGET_UNAVAILABLE before TARGET_EVENT_HALTED is is sent in
halt_finish(), because that's what triggers hwthread_update_threads(),
which must know about unavailable harts so they can be hidden from gdb.

When SMP is enabled, gdb will always use the first target in the SMP
group. That doesn't work when that first target is unavailable, but
others in the SMP group are still available.
For cases where gdb expects an operation to affect the entire group (run
control, memory access), find the first available target in an SMP group
and use that.

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.

* [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 was used to track which hart a given operation must apply to. But
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.

Note that the ".0" is for the first such instance of the variable as a

Requested in https://review.openocd.org/c/openocd/+/6964.
I'm making the change here so I have a chance to test it properly before
pushing it upstream.
A nice effect of this change is that we avoid some unnecessary polling
early on when gdb is connecting and we would poll once every time we
send gdb a qXfer packet.

This updates the FreeRTOS module to use the M4F FPU stacking also for the
FPV5_SP and FPV5_DP FPUs, which are found on the Cortex-M7. The FPUs are
in fact different than the FPV4_SP found on the M4, but the register
stacking is the same.

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.
