Detailed Description

SCB fault-status register snapshot.

sfsr / sfar are the ARMv8-M Security Extension fault pair. They are banked to the Secure state: read from the Secure world (where every boot in this repository executes) they carry the SecureFault cause bits (INVEP, INVTRAN, AUVIOL, ...) and the faulting address; read from the Non-secure world they are architecturally RAZ, so the unconditional capture is safe in either world.
