Musca S1: Erase PS area in QSPI flash #108

Closed LDong-Arm closed 3 years ago

LDong-Arm commented 3 years ago

TF-M v1.3 has relocated the Protected Storage (PS) area on Musca S1 from MRAM to QSPI flash. The area is memory mapped, so we can erase it with the regular hex images.

PSA storage areas (PS and ITS) are erased to avoid residual data interfering with storage test cases.

Note: This solves the Protected Storage test failures on my local Musca S1 board.

Doesn't seem to work this time, need to find out what's happening...
