When MCUBOOT repo: UPSTREAM was set as default as part of TF-M 1.1
release, few things were changed:
MCUBOOT_IMAGE_NUMBER: '2'
MCUBOOT_UPGRADE_STRATEGY: 'OVERWRITE_ONLY'
MCUBOOT_HW_KEY: 'On'(default)
Therefore the signing strategy for Non-secure image (Mbed OS)
needs to be done with its own private key, which is validated during
boot.

The API is_PSA_non_secure_target() uses obsolete labels to detect if a
target is PSA non-secure target and is not needed anymore.
Mbed OS depends on TF-M for PSA SPM and services. TF-M is built using
it's own build system. Therefore, we don't need to differentiate secure
and non-secure targets anymore in Mbed OS as all PSA targets in Mbed OS
are non-secure targets.

Current logic `is_TFM_target` relies on the availability of attribute
`tfm_target_name` to identify PSA targets. The API `is_TFM_target` is
used in pytest to validate PSA target configuration which again checks
the availability of `tfm_target_name`. If a target doesn't contain the
attribute `tfm_target_name` then this check will fail instead of
catching it. Therefore, we now check for `TFM` config option in `labels`
attribute.
The API `is_TFM_target()` returns true for Mbed OS PSA targets which are
supported by TF-M also.
Add a new API `is_PSA_target()` which returns true for all Mbed OS PSA
targets.

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`

When python3 is enforced to build the ARM_MUSCA_A1 or ARM_MUSCA_B1
targets, it is unable to find binary utility tool scripts which are
imported from TF-M.
The reason to use the python3 environment is as follows: Mbed OS + TFM
contained a faulty boot record TLV, which failed the attestation test
(TF-M regression). The data in the boot record TLV will be included in
the generated attestation token as 1 item in the SW_COMPONENTS claim.
This data (in the boot record TLV) is pre-encoded in CBOR format at
build time and appended to the image during the image signing process
(done by the imgtool Python3 script).

Give a warning rather than error if an unrecognised feature is used.
This will help compatibility when new features are added.
Signed-off-by: Darryl Green <darryl.green@arm.com>
For backwards compatibility reasons, since the latest Mbed OS tools must
be able to build any previous online-compiler-supported version of Mbed
OS, allow targets to use `default_lib` or `c_lib`. This should enable
the tools to work with Mbed OS 5 style targets.json.
- This change will cause build-system to produce both .bin and .hex files.
- Files are small and their creation is fast, thus there are no negative impact
on build time and storage requirements.
- .bin files are required for updating the device
- .hex files are very handy for post build (external to build system) custom
scripts (e.g. image signing)
- Configuration still allows selecting either .bin or .hex files, this settings is still
relevant as it specifies what file is flashed to a device for tests or by
`--flash` argument.
For backwards compatibility reasons, as the Mbed tools must be able to
build any online-compiler-supported version of Mbed, revert back to
emitting a warning when ARMC5 is used. This will enable ARMC5 to
continue working in the online compiler for Mbed OS 5 and other previous
versions. ARMC5 remains unsupported in Mbed 6.
This reverts commit 03d57b7ba2.
We cant afford to raise an exception now. As anyone using this out there do not catch it. Rather
an empty list, as it can work after this fix - won't do anything.
This is non trivial fix as the function is being used outside of this repository.
Tools rely on it to return list of targets for 2 or 5. As we removed release_version from many targets,
this broke the logic. To keep the logic as it was, without updating all tools out there now,
lets just return full set of targets - all are supported.
In case for Mbed 2, returning all targets does not make sense, but rather raise an exception here. Not supported. This avoids suprised. If you look at build api functions there are many checks for 2 or 5 so more
clean up needed to actually get release_version out of the tools.
cherry pick otherwise fails because the sources were moved under rtos/source. I manually resolved these patches. For the future, lets use these newer sha that should work.

For release and develop profiles, turn on the linker's `--inline`
optimisation. This can save a couple of hundred bytes in a typical
image.
The optimisation replaces branches to small functions with the
inlined code from those functions. And it's possible that the
out-of-line functions can be eliminated.
Setting confined to release and develop builds only, as it can lead to
invalid debug information.
Display a post-build warning indicating to the user that the standard C
library was used instead of the small C library if the former is not
supported.
We disable C++ static destructors as best as possible in the various
toolchains, trying to eliminate unwanted destructor code. We don't want
to waste RAM or ROM on the C++-standard-specified behaviour of running
all statically-constructed objects' destructors in reverse order on
exit; we're never going to perform an orderly exit.
Techniques used include:
* `SingletonPtr` - makes an object be "lazily constructed" on first use,
and also eliminates its destructor. Lazy construction adds ROM+RAM
overhead.
* `__eabi_atexit` is stubbed out, preventing RAM usage by run-time
registration of static destructors.
* GCC has `exit` wrapped to kill shutdown code
* IAR has static destructors disabled in the compiler flags
Killing static destructors in the compiler is the optimum; if we only
stub out `__eabi_atexit`, the compiler is still inserting calls to it,
and referencing the destructors in those call.
Clang 8 added the compiler option `-fno-c++-static-destructors` (and the
object attributes `[[clang::no_destroy]]` and
`[[clang::always_destroy]]` for fine control).
We can hence enable that option in ARMC6 tool profiles, matching IAR.
This option appears to exist in ARM Compiler 6.11, but generates an
apparently spurious linker error about `EthernetInterface`. It works in
ARM Compiler 6.13, so this PR needs to wait until the compiler is
updated.
* Add optimised constexpr default constructor. Default construction
was previously by a heavyweight defaulted `nsapi_addr_t` parameter.
* Remove deprecated resolving constructor.
* Take `nsapi_addr_t` inputs by constant reference rather than value.
* Inline the trivial getters and setters.
* Use `unique_ptr` to manage the text buffer.
* Make `operator bool` explicit.
* Optimise some methods.
* Update to C++11 style (default initialisers, nullptr etc)

Master branch contains lot of missing SPDX identifiers, we will clean them up but this will take some time. In the meantime, we should not increase the license missing files. Each PR will report if there is no license issue or positive number reported as Github status. Travis won't fail if there are issues. This will highlight the issues that anyone can fix.

The goal: check license offenders in pull request
This is similar to what astyle does in Travis. We get list of files being changed. Because scancode does not support list of files being scanned but rather a file or directory, we copy files to SCANCODE folder. Execute scancode license check in this folder and check for offenders.
The rules there are: code files must have a license and SDPX identifier. If they don't, we print these and ask for review.
It functions nicely there is just one workaround needed. SPDX is not always 100 percent correctly found, therefore we recheck file if no SPDX manually in the script. This proves to remove false positives.
For bootloader enabled target, it needs to have cmsis pack or provide memory override. This change fixes build failure in case of no cmsis pack but providing memory override with start being zero.
This is a workaround for the GCC not using the strong symbols from
C files to override the weak symbols from ASM files. This GCC bug is only
present when building with the link-time optimizer (LTO) enabled. For
more details please see:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83967
This can be fixed by changing the order of object files in the linker
command; objects providing the weak symbols and compiled from assembly
must be listed before the objects providing the strong symbols.
To keep things simple, ALL object files from ASM are listed before
other object files.
Disable the lto for the default develop and release prifiles and move
the flags to tools/profiles/extensions/lto.json profile.
Usage:
mbed compile --profile release --profile tools/profiles/extensions/lto.json
This fixes the undefined reference to 'main' that arose after adding
the "-flto" flag to compilation.
This was the case for combined "-Wl,--wrap,main" and "-flto" flags.
According to GCC man:
To use the link-time optimizer, -flto and optimization options should be
specified at compile time and during the final link. It is recommended
that you compile all the files participating in the same link with the
same options and also specify those options at link time.
Additionally, move the '-g3' flag out of 'common' flags in the debug
profile. Although the '-g' is correctly ignored by the linker, the
'-glevel' is not and causes a build error "ld: unrecognized option
'-g3'".

This call to sorted does nothing in Python 2, as there is no way to sort a list

In Python 3 this call fails with an error as there is no comparison implemented

This is fixed by providing the key str, which sorts by the str representation of

- 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

We removed catching and passing, we want to know for any misconfiguration if bootloader
is supported. Regions should check if bootloader is supported. In case not, just return.
Otherwise we catch any error.
This should help us to uncover missing regions or other config error (in case bootloader
is enabled via bootloader_supported set to true).
Currently any misconfiguration of, for example, bootloader feature will cause the
build system to just silently drop it and continue building which can lead to
completed builds of something the user didn't want to build in worst case and
failing builds after compilation (=wasted time) in the best.
For GCC we're being cautious by passing the
`-fno-delete-null-pointer-checks`. This option prevents some
optimisation opportunities, so removing it can reduce code size.
One particular optimisation loss occurs in `Callback` where a test
similar to this occurs:
extern void myfunc();
inline void foo(void (*fnptr)())
{
if (fnptr) {
do A;
} else {
do B;
}
};
foo(myfunc);
With `-fno-delete-null-pointer-checks`, the compiler does not assume
that `&myfunc` is non-null, and inserts the "null check" - seeing if the
address is 0. But performing that test of the address is incorrect
anyway - if myfunc actually could be at address 0, we'd still want to do
A.
Anyway, we do not have an equivalent option enabled for either Clang or
IAR, and we have performed clean-ups avoiding issues with
apparently-null vector tables in Clang already, for example #10534.
Therefore it should(TM) be safe to remove the option for GCC. We do not
have general data or code at address 0, only vectors are likely to be
there, so it does not make sense to be globally restricting code
generation for that.
Planning to update to supporting GCC 9 as found in GNU Tools for Arm
Embedded Processors 9-2019q4-major.
Newer GCC in particular supports ARMv8-M security extensions, and
link-time optimisation - two areas of interest.
Should be no code changes required, but need to change the warning in
the toolchain script.
- add --inline option to linker flags
Some routines are so small that they can fit in the space of the
instruction that calls the routine. Use this option to make the
linker replace the call of a routine with the body of the routine,
where applicable.
Currently mbed-os-example-blinky and mbed-os-example-wifi are built for each and every target in Mbed OS. This will change that only DISCO_L475VG_IOT01A is built for mbed-os-example-wifi. DISCO_L475VG_IOT01A was chosen as its one of the wi-fi supported boards and having integrated wi-fi.
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"`.
