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)

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).

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.
Enabled heap_and_stack test for baremetal.
Added a test to check that global variables are initialised.
In mbed_sdk_boot:
- Added initialisation for mbed_stack_isr_start/size and mbed_heap_start/size for all toolchains.
- ARM toolchain:
- Added call to mbed_toolchain_init() to initialise global variables.
- Moved microlib initialisation code from mbed_retarget.cpp to mbed_sdk_boot.c.
- IAR toolchain: there is no equivalent to a software init hook that can be called. __low_level_init() was used but since this function is called before RAM initialisation, it cannot be used to initialize global variables. Defined a new __mbed_init() function called from IAR startup file instead.
- By default, Mbed OS build tools use standard C library for all supported toolchains.
It is possible to use smaller C libraries by overriding the "target.default_lib" option
with "small". This option is only currently supported for the GCC_ARM toolchain.
This override config option is now extended in the build tool for ARM toolchain.
- Add configuration option to specify libraries supported for each toolchain per targets.
- Move __aeabi_assert function from rtos to retarget code so it’s available for bare metal.
- Use 2 memory region model for ARM toolchain scatter file for the following targets:
NUCLEO_F207ZG, STM32F411xE, STM32F429xI, NUCLEO_L073RZ, STM32F303xE
- Add a warning message in the build tools to deprecate uARM toolchain.
- NewLib-Nano C library is not supporting floating-point and printf with %hhd,%hhu,%hhX,%lld,%llu,%llX
format specifier so skipping those green tea test cases.
Build successfully when `platform.stdio-convert-tty-newlines` or
`platform.stdio-convert-newlines` are set to `true` by ensuring
`isatty()` is also included when `platform.stdio-minimal-console-only`
is set to `true`.
The retarget code allocates an array of FileHandle* for console and file
handling (filehandles). A tiny target only needs a console (putc/getc).
There is no need for file handling.
The POSIX layer and the array of FileHandle* is not required for small
targets that only need a console ; this code is optionally compiled
out if the configuration parameter platform.stdio-minimal-console-only is
set to `"true"`.
Locating and checking the length of the `ARM_LIB_HEAP` region is an
extra task, when we're just interested in the base and limit. Looking at
only those saves 8 bytes of ROM.
More space could be saved if we ensured all targets had `ARM_LIB_HEAP`,
removing the need for this run-time fallback code.
When moving to the second heap region due to overflowing the first
region, the `_sbrk` implementation assumed the allocation would fit in
the second region, and didn't check for that overflowing too.
Problem revealed in `stats_heap` test with GCC 8 on K64F - the allocation
attempt for 1GiB crashed, as `_sbrk` indicated 1GiB was available at the
start of the second region.
second region.
Presumably older versions of newlib fault that allocation attempt before
passing to `_sbrk`.
While there, adjust the code to not use a separate static `bool`, saving
RAM. We can track with just one pointer, as order of the two regions is
fixed, and already relied on by newlib.
The ARMC6 compiler inadvertently introduces the `_scanf_mbtowc` symbol
to the build. The commit provides a weak definition of the symbol to
satisfy the linker whenever the symbol is included. This affects ARM
Compiler 6 version 6.12 and earlier.
The compiler error was previously observed when the MICROLIB library is
used with the uARM toolchain. However, the weak definition was put in
`mbed-os/rtos` which is not included when the bare metal profile is used.
Also includes:
* rename `mbed_sleep_manager.c` to `mbed_power_mgmt.c` to match its
header file
* create Doxygen groups for public and internal APIs
* use relative path to include header files where inconsistent
* update references to internal APIs throughout libraries
* update the copyright year for all modified files
