Thus far the default position has been after the application plus two
spare sectors. For simplicity and to have a predictable location for the
TDBStore with the default configuration the location is now switched to
the end of the flash. Two last sectors to be exact.
Macro which restricted compilation to GCC_ARM is removed.
Existing read_write() test is amended to call stat() and check that correct size is returned.
- Add the no confidentiality & no replay protection flags
- Add actual size parameter in PS/ITS get APIs
- Change a few size parameters from uint32_t to size_t
Musca-A1 is a Cortex-M33 based target with security extension enabled.
- ARM_MUSCA_A1 is the non-secure target running mbed-os.
- ARM_MUSCA_A1_S is the secure target running TF-M.
- TF-M sources were imported and patched in previous commits.
- TF-M secure bootloader (McuBoot) for MUSCA_A1 is submitted by a pre-built binary.
- A post-build hook concatenates The secure and non-secure binaries,
signs it and then concatenates the bootloader with the signed binary.
due to partial implementation. Having FUTURE_SEQUANA_M0 and
FUTURE_SEQUANA PSA targets is misleading.

Reimplement atomic code in inline assembly. This can improve
optimisation, and avoids potential architectural problems with using
LDREX/STREX intrinsics.
API further extended:
* Bitwise operations (fetch_and/fetch_or/fetch_xor)
* fetch_add and fetch_sub (like incr/decr, but returning old value -
aligning with C++11)
* compare_exchange_weak
* Explicit memory order specification
* Basic freestanding template overloads for C++
This gives our existing C implementation essentially all the functionality
needed by C++11.
An actual Atomic<T> template based upon these C functions could follow.
One gets this compiler warning from nvstore.cpp:
```
Compile [ 48.6%]: nvstore.cpp
[Warning] nvstore.cpp@814,9: variable 'os_ret' set but not used [-Wunused-but-set-variable]
```
Turns out it's caused by the fact that the variable is only used
with MBED_ASSERTs, which get optimized out or not, depending on your
build profile. In reality we do not need a separate variable for that
in my opinion though, so we can just use the ret-variable instead
and drop the os_ret variable completely and thus avoid this
compiler warning.
To support block device out of mbed-os tree in KVStore, user needs to:
1. Configure blockdevice to "other".
2. Override get_other_blockdevice() to provide block device out of mbed-os tree.
Due to discovery of inconsistent sector sizes in devices storage the is_valid_erase function was adjusted,
For FlashIAPBD the 'code size' was included to the calculation, preventing faulty "virtual" addresses calculation.
For SlicingBD the same error was fixed and in all 3 validation functions that sent addresses for validation and program/read/erase
different addresses.
