target: add "phys" argument to mem2array, array2mem
Allow using physical addresses with mem2array and array2mem. In order
to minimize the impact on existing scripts, "phys" is added as an
optional 5th parameter to both commands.
This patch also adds "phys" variants to the memwrite/memread commands
in memory.tcl.
Sometimes it is necessary to resume into a different state (ARM/Thumb)
than at debug state entry. According to the documentation this should
be possible with "arm core_state arm|thumb" before the resume command,
however the original code also restores the original CPSR, which
overrides whatever state the core was set to. This seems to work on some
cores (e.g. Cortex-A5) but not on others (e.g. Cortex-A9). Using the "BX"
instruction to set resume PC and core state works on Cortex-A9 and
ARM11, but is not sufficient on Cortex-A5, where an explicit write to
the PC (MOV pc, r0) is required additionally.

1986VE1T and 1986VE3T have issue with flash acceleration engine described

After programming flash acceleration engine's buffer contains old data,
and therefore first read data are wrong. Because of this verification after
programming fails always. Recommended workaround for the issue is to flush
flash accelerator's buffer. To do so it's necessary to read at least 64

target: improve robustness of reset command
Before this change jim_target_reset() checked examined state of a target
and failed without calling .assert_reset in particular target layer
(and without comprehensible warning to user).
Cortex-M target (which refuses access to DP under active SRST):
If connection is lost then reset process fails before asserting SRST
and connection with MCU is not restored.
This resulted in:
1) A lot of Cortex-M MCUs required use of reset button or cycling power
after firmware blocked SWD access somehow (sleep, misconfigured clock etc).
If firmware blocks SWD access early during initialization, a MCU could
become completely inaccessible by SWD.
2) If OpenOCD is (re)started and a MCU is in a broken state unresponsive
to SWD, reset command does not work even if it could help to restore communication.
Hopefully this scenario is not possible under full JTAG.
jim_target_reset() in target.c now does not check examined state
and delegates this task to a particular target. All targets have been checked
and xx_assert_reset() (or xx_deassert_reset()) procedures were changed
to check examined state if needed. Targets except arm11, cortex_a and cortex_m
just fail if target is not examined although it may be possible to use
at least hw reset. Left as TODO for developers familiar with these targets.

Errors from less important reads/writes are ignored.
Requested reset always leads to a configured action.

inline-commenting the THUMB bytecode, place the hex array alongside the
assembler sources and include it via preprocessor.
Originally inspired by a typo in the file path during driver development,
but it also facilitates making changes to the assembler sources.
A Makefile is provided to help automate updating the bytecode. It is not
integrated with the automake system to avoid forcing an ARM cross-compiler
onto every user, i.e. after modifying the sources they need to be rebuilt
in that directory before building the usual way. ARM_CROSS_COMPILE= can
be passed on the make command line to deal with native ARM toolchains
or with varying prefixes of cross-toolchains.

flash: New Spansion FM4 flash driver
The Spansion FM4 family of microcontrollers does not offer a way to
identify the chip model nor the flash size, except for Dual Flash vs.
regular layout. Therefore the family is passed as argument and
wildcard-matched - MB9BFx6x and S6E2CC families are supported.
Iterations showed that ...
1) Just doing the flash command sequence from SRAM loader code for each
half-word took 20 minutes for an 8 KB block.
2) Doing the busy-wait in the loader merely reduced the time to 19 minutes.
3) Significant performance gains were achieved by looping in loader code
rather than in OpenOCD and by maximizing the batch size across sectors,
getting us down to ~2 seconds for 8 KB and ~2.5 minutes for 1.1 MB.
(Tested with SK-FM4-176L-S6E2CC-ETH v11, CMSIS-DAP v23.)
gcc, objcopy -Obinary and bin2char.sh are used for automating the
integration of hand-written assembler snippets.

tcl/target/stm32f4: fix: reduce adapter speed before reset
The reset-init hook for this target speeds up the CPU clock and JTAG adapter
speed. When the target is reset running with high adapter speed, a series of
warnings "DAP transaction stalled (WAIT) - slowing down" will be generated
since the adapter speed is not reduced to fit the slower CPU speed.
Fix: reduction of the adapter speed before a reset is performed.
