Set up halt groups for SMP groups. (#353)
If the hardware supports it, when one hart in an SMP group halts all the
other harts in that same SMP group will automatically, quickly, halt as
well.

Rtos riscv (#350)
* Implement riscv_get_thread_reg().

This is necessary because riscv_get_gdb_reg_list() now reads all
registers, which ended up causing `-rtos riscv` to read all registers
whenever one was requested (because the register cache is wiped every
time we switch to a different hart).

CustomRegisterTest went from 1329s to 106s.

Change-Id: I8e9918b7a532d44bca927f67aae5ac34954a8d32

* Also implement riscv_set_reg().

Now all the `-rtos riscv` tests pass again, at regular speed.

Change-Id: I55164224672d9dcc9eb4d1184b47258ff3c2cff1

* Better error messages.

Change-Id: I4125f9a54750d9d0ee22c4fa84b9dd3f5af203f5

* Add target_get_gdb_reg_list_noread().

Being explicit about what's expected gets `-rtos riscv` back to `-rtos
hwthread` time.

Change-Id: I6e57390c2fe79b5e6799bfda980d89697e2e29f7

* Revert a change I made that has no effect.

I don't understand exactly what all this test protects against, and I
shouldn't change it unless I do.

Tomas Vanek 7a3eec2b4d target algo: do not write reg_param if direction is PARAM_IN
Without this change xxx_start_algorithm() writes all register
parameters no matter of their direction. It usually results
in writing of uninitialized reg_params[].value - possibly
reported by valgrind.

While on it fix the wrong parameter direction in
kinetis_disable_wdog_algo(). This bug did not have any
impact because of unconditional write of reg_params.

Tomas Vanek 4b998cb5f5 cortex_m: fix stepping on FPB rev 1
Stepping in the maskisr auto mode sets breakpoint to step over interrupt
service tasks. If the device has FPB rev 1, setting hard breakpoint
is impossible on address over 0x1fffffff.

Use soft type breakpoint for adresses over 0x1fffffff if FPB is rev 1.
This may eventually fail if the code memory is not writeable, but there
is nothing to do in such case.

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.

Antonio Borneo 3799eded67 target/aarch64: add support for multi-architecture gdb
GDB can be built for multi-architecture through the command
	./configure --enable-targets=all && make
Such multi-architecture GDB requires the target's architecture to
be selected either manually by the user through the GDB command
"set architecture" or automatically by the target description sent
by the remote target (i.e. OpenOCD).

Commit e65acd889c ("gdb_server: add
support for architecture element") already provides the required
infrastructure to support multi-architecture gdb.

aarch64-linux-gnu-gdb 8.2 uses "aarch64" as default architecture,
but also supports the value "aarch64:ilp32" and all the values
supported by arm-none-eabi-gdb.
These values can be displayed on arm gdb prompt by typing
"set architecture " followed by a TAB for autocompletion.

Set the gdb architecture value for aarch64 target to "aarch64".

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.

This commit adds TARGET_HALTED check in armv8_get_core_reg32()
and armv8_set_core_reg32() to void a crash issue when gdb connects
but fails to halt the ARM core. Similar logic can be found in
armv8_get_core_reg() and armv8_set_core_reg().

Below is the call stack information of this case when gdb connects.

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.
