 - fix for alignment faults under high memory pressure

 - use u32 for ARM instructions in fault handler

 - mark functions that must always be inlined with __always_inline

 - fix for nommu XIP

 - fix ARMv7M switch to handler mode in reboot path

 - fix the recently introduced AMBA reset control error paths
