Fixes two errors produced on except.S by the IAR assembler (as seen in
issue #13200).
The first: "'ALIGN' is illegal. Use directive ALIGNROM or ALIGNRAM (the
first parameter is raised to the power of 2, the second is a 32-bit fill
value)."
Fixed by changing ALIGN to ALIGNROM 2 to align to a 4-byte boundary
(mirroring what ALIGN does in the ARM except.S).
The second (on THUMB): "Must be placed inside a section"
Fixed by moving THUMB after the SECTION directive so that it affects
that section.
Add TF-M to Mbed OS, replacing the previous PSA implementation for
TF-M-capable targets. This commit adds files imported from TF-M, without
modification. The version of TF-M imported can be found in
`features/FEATURE_PSA/TARGET_TFM/VERSION.txt`.
These changes switch to TF-M as the sole PSA implementation for v8-M and
dual core targets, with TF-M running on the secure side and Mbed OS
running on the non-secure side. Single core v7-M targets will continue
to have PSA implemented via PSA emulation, implemented by Mbed OS.
Move or remove many PSA-implementing files, as PSA will be provided by
TF-M on non-single-v7-M targets. Delete any files that are not relevant
for PSA emulation mode.
- Remove imported TF-M SPM
- Remove Mbed SPM and tests
- Remove Mbed-implemented PSA services and tests
- Remove PSA_SRV_IMPL, PSA_SRV_IPC, PSA_SRV_EMUL and NSPE.
- Replace PSA_SRV_EMUL and PSA_SRV_IMPL with MBED_PSA_SRV
- Remove any files autogenerated by
"tools/psa/generate_partition_code.py", which no longer exists.
Add new feature `PSA` to support PSA in Mbed OS.
Move the Mbed OS implementation of PSA services for v7-M targets (which
employ PSA emulation, and don't yet use TF-M) to
features/FEATURE_PSA/TARGET_MBED_PSA_SRV. Update the `requires`
attribute in TESTS/configs/baremetal.json to avoid breaking baremetal
testing builds.
Update .astyleignore to match new directory structure
Update Mbed TLS importer to place files into FEATURE_PSA
Create the following generic PSA targets:
* `PSA_Target` (Root level PSA generic target)
* `PSA_V7_M` (Single v7-M PSA generic target)
* `PSA_DUAL_CORE` (Dual-core PSA generic target)
* `PSA_V8_M` (v8-M PSA generic target)
Flatten MUSCA_NS and private MUSCA targets into public MUSCA targets.
Move mcuboot.bin to flat location (removing prebuilt folder)

Chrono conversions inadvertantly changed the core timed sleep routine
used by the RTOS idle to use `OsTimer::update_and_get_tick()` instead of
`OsTimer::get_tick()`.
Correct this, and expand/clarify documentation and naming to try to
prevent recurrence.
Another minor fix observed while inspecting code - `OsClock` can't just
use `milliseconds`, it should match the period of `OsTimer`, which
theoretically can be different.
Remove all PSA S-mode only code, as it is unused. Only PSA S targets
would use the code, and we've removed those targets in a previous
commit.
Ensure all tests for S-mode code we are deleting is also removed, even
if that code would run in NS-mode. Keep any tests that also test our PSA
emulation support (for single v7-M targets).

* Timer test - handle removal of Timer(ticker_data_t *)
* Timer test - use Chrono, don't test deprecated methods
* Kernel tick count test - TEST_ASSERT_WITHIN -> TEST_ASSERT_INT_WITHIN
* Mutex test - fix up Chrono changes
* SysTimer test - adapt to SysTimer Chrono changes
* Thread test - use Chrono
* SysTimer - devirtualize destructor
Use correctly-typed external definition for the crash data region, and
eliminate unnecessary pointer indirection.
Results in a small ROM saving even with crash capture disabled, as there
was a pointer for the fault context store in either case. The pointer
isn't needed, as the context store location is fixed according to the
configuration flag.
Return the correct filehandle based on the mode requested. The mode is used
as the pathname is always the default one (":tt") for Microlib. The
previous implementation relied on three successive calls to open the std
I/O device handles, this was not the case.
mbed_minimal_putchar assumed that buffer being NULL meant that it
should print to a file. This caused a system crash when calling
snprintf with both buffer and stream set to NULL.
It is valid to call snprintf with a NULL buffer; nothing should
be outputted, but the string length should be measured.
This code prevents the ARMC6 compiler/linker from removing
SUB_REALLOC/CALLOC symbols from image when LTO is enabled
Fixes below error:
L6137E: Symbol $Sub$$calloc was not preserved by the LTO codegen but is needed by the image.
