This task updates the SST service to call into the Crypto service instead of using Mbed TLS. Reference to Mbed TLS build are removed from the SST service as part of this task.
Additional patch: https://review.trustedfirmware.org/c/trusted-firmware-m/+/1147
The previous patch has been reworked to be split in two different patches to allow better clarify on the scope of the patches themselves:
1076: Build changes and interfaces changes in SST
1147: Reduce required stack size in SST as result of Crypto binding.
