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)

Assert it properly and thus give out the target name where the
issue is, rather than just error out with KeyError and leave the
poor sod wondering where exactly the issue is.
Before:
```
=================================== FAILURES ===================================
_____________________________ test_bl_has_sectors ______________________________
def test_bl_has_sectors():
"""Assert a bootloader supporting pack has sector information"""
cache = Cache(True, True)
named_targets = (
target for target in TARGETS if
(hasattr(target, "device_name") and getattr(target, "bootloader_supported", False))
)
for target in named_targets:
assert target.device_name in cache.index,\
("Target %s contains invalid device_name %s" %
(target.name, target.device_name))
> assert cache.index[target.device_name]["sectors"],\
("Device name %s is misssing sector information" %
(target.device_name))
E KeyError: 'sectors'
```
After
```
___________________________________________________ test_bl_has_sectors ___________________________________________________

(target.name))
E AssertionError: Target NUCLEO_L073RZ does not have sectors
E assert 'sectors' in {'algorithms': [{'default': True, 'file_name': 'CMSIS/Flash/STM32L0xx_192.FLM', 'ram_size': None, 'ram_start': None, ....on_secure_callable': False, 'peripheral': False, ...}, 'default': True, 'size': 196608, 'start': 134217728, ...}}, ...}
```
This helps you finding the offending target a bit faster.
Kudos to Jammu Kekkonen (jammu.kekkonen@arm.com) to figuring out how to actually
run this test & the assertion.
