Update the current version of mbed TLS with the development HEAD of the
mbed TLS project repository. This mostly includes the latest CMAC
feature. Also, update the version in the importer Makefile and
VERSION.txt with the hash of the mbed TLS commit that was sync'ed.
to mbed SDK as there are targets with Cortex-M4. This is similar to the implementation already
done for GCC ARM

Supported toolchains initialization steps have been modified to make sure
that mbed_sdk_initi is called _after_ RAM initialization and _before_ C++
objects creation.
since this was done, there is no need to redundant SystemCoreClockUpdates
in the drivers
Various toolchains supported in MBED don't followthe same initialization
steps. This can have impacts on platform behavior.
For STM32, it is needed to call the HAL_Init() _after_ the RAM has been
initialized (sdata from flash / zero initialized data) and _before_ the C++
objects are being created, especially if those objects require support
of tickers for instance.
In GCC and IAR, this was done in previous commit to avoid HAL_Init()
to be called twice.
In ARM this there is no hook defined in MBED yet to place the call.
The proposal is to take benefit of the library's
_platform_post_stackheap_init function that is going to be called before
__rt_lib_init where the C++ object init is done (__cpp_initialize__aeabi_)
In case of mbed with rtos, the __rt_entry is redefined so we need to add
the call to _platform_post_stackheap_init.
This series should solve issue reported here:
STM32 (At least F401) breaks if Tickers are activated in a global object #2115
In uARM, the library's hook _platform_post_stackheap_init does not seem to
exist and I couldnot find a documentation describing the initialisation
flow. All we know is that _open is called after RAM init and before the
C++ init, so this is a working placeholder.
This is maybe not acceptable so a uARM lib expert may propose a better
hook to fullfil the requirement.
At least this is a workign setup.
