armv4_5: support weirdo ARMv6 secure monitor mode

On the ARM PB1176JZF-S the system comes up in secure monitor
mode after reset. However the modebits in CPSR form the value
28 (0x1c) and CPSR is 0x800001dc deeming it UNRECOGNIZED.
Define this mode to be synonymous to mode 22 (MON) and things
start to work like a charm.

xmc4xxx: Integrate build of erase check code

Instead of pointing to the assembler sources in a comment and
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.

sufficient to get device to normal RUN.

adiv5: introduce optional dap_sync() function

dap_sync() executes all commands in the JTAG queue and then checks
if a WAIT condition happened inside the last batch. If yes, a recovery
is invoked. If not, processing continues without checking for
errors. This function should be called in long AP read or writes, e.g.
while uploading a new application binary, at intermediate points within
the transfer where the cost of flushing the JTAG queue and checking the
journal doesn't affect performance too much.

adi_v5_jtag: implement DAP WAIT support

ADIv5 specifies that DP and AP accesses may generate a WAIT
response when the hardware is not able to complete a request for various
reasons in time before the next request is sent. Currently, the software
treats a WAIT response as a fatal error and aborts operation on the DAP.

This patch implements WAIT handling by keeping a journal of all
outstanding and completed accesses, including their response status.
At certain times (when dap_run() is called), the journal is inspected
for WAIT responses and all discarded accesses are replayed to complete
them. Special care is taken to not re-execute already successfully
completed operations.

ARM ADIv5: CoreSight ROM decode part number and designer id

The existing arm_adi_v5.c code decodes CoreSight peripherals based
on the part number field.  However, these are specific to a
particular manufacturer (often ARM).  The same part number from
two different manufacturers (distinct designer ids) should not
decode as the same CoreSight peripheral.

The Analog Devices ADSP-SC58x and ADSP-BF70x have peripherals that
overlap with existing OpenOCD decoding.  The part number is the
same as existing OpenOCD decoding, but have a different JEP106 code.

Most, if not all, of the existing part number entries in
arm_adi_v5.c are probably specific to ARM. Change all entries
suspected to be designed by ARM to match only ARM's designer ID.

However, to preserve legacy behavior, existing non-ARM entries are
encoded with a wildcard so that they will behave in the same way as
the existing legacy code.  It is desirable, however, to start
encoding the data with designer codes to avoid such ambiguity.

Revising the code to check both the part number and designer id
seemed to a warrant a const array lookup table instead of a
multi-tiered switch statement.

Also try to sync part identification IDs with relevant ARM docs.

arm_debug: optimize DP and AP reads over JTAG

On JTAG, all reads are pipelined. If you read a register, the result is not
delivered inside the request that issued the read, it is delivered in the
following request. The current code therefore issues a scan of the RDBUFF
register after each read. This adds a superfluous transaction after each
read.

This patch follows a strategy similar to what SWD already implements.
It also leverages that all JTAG reads are pipelined, i.e. the result
will be clocked out in the next JTAG data phase, no matter if it's
READ or WRITE. Therefore it's never necessary to explicitly read RDBUFF
other than for the very last READ before a dap_run().

However, AHB-AP is the wrong choice, because it bypasses caches on read

caches). This patch explicitely selects the APB-AP (debug_ap) as the

arm_adi_v5: Convert the AP references from numbers to pointers

Change the debug_ap and memory_ap fields of the cortex_a target and
the debug_ap field of the cortex_m target to be pointers to the
struct adiv5_ap instead of AP numbers in some known DAP.

This reduces the dependency on the DAP struct in the targets and
enables MEM-AP accesses to take the relevant AP as parameter.

arm_adi_v5: Add a back-pointer from an AP to its DAP

This will make it possible to reference directly the AP used for debug
in the target instance and remove the DAP reference. This will in turn
enable getting rid of the need to select an "active" AP in the DAP (using
dap apsel).

target/arm: Remove usage of struct arm_jtag in ARMv7 targets

The Cortex-A and Cortex-M keeps an arm_jtag struct around just to be
able to pass a pointer to it to one common JTAG function which anyway
only uses the TAP field.

Refactor the function to take a TAP directly, remove the legacy struct
from cortex instances and store the TAP pointer only in the DAP.

Cortex-M makes a call to arm_jtag_setup_connection() with the struct
but the function does nothing useful for a Cortex-M target so remove
the call.

swd: Remove DAP from parameter list

Making the SWD driver aware of the DAP that controls it is a layering
violation.

The only usage for the DAP pointer is to store the number of idle cycles
the AP may need to avoid WAITs. Replace the DAP pointer with a cycle
count hint instead to avoid future misuse.

arm_debug: Support multiple APs per DAP and remove DAP from armv7* structs

Separate out the values from adiv5_dap that are associated with a specific AP into a new struct, so we can properly support multiple APs. Remove the DAP struct from the armv7* structs, because we can have multiple CPUs per DAP, and we shouldn't have multiple DAP structs. Tidy up a few places where ap_current is used incorrectly.

cortex-a: Fix "Detected core" number is always '0'

Problem
No matter what target->coreid is, it always shows
Detected core 0 dbgbase: ...

In dap_lookup_cs_component(), it decreases the core index value to zero
in order to find the desired core.
The reference to coreidx is necessary considering "a device which has nested
ROM tables, with each core described in its own table." (by Paul Fertser).
