https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/802/ is implementing the 8 bytes minimum write access.
As ConfigRegression.cmake uses by default a RAM_FS for SST , it can used to test this patch on any platform.
In flash_layout.h
#define SST_FLASH_PROGRAM_UNIT 8
For now, this patch is functional without encryption.
set (SST_ENCRYPTION OFF)

With https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/806/
Regression test is now passed with set (SST_ENCRYPTION ON)
