The StandaloneMM image executes in S-EL0 on reference Arm platforms and is deployed by the trusted firmware as BL32 image. Memory for the Standalone MM drivers is marked as RW+XN initially, allowing the drivers to be loaded into the memory. Once loaded, the memory attributes need to be changed to RO+XN for rodata sections and RO+X for code sections. Achieve this through the extra action 'UpdatePeCoffPermissions' to request the privileged firmware in EL3 to update the permissions.
