Subject: [edk2-devel] [PATCH] StandaloneMmPkg/StandaloneMmMemLib: Update AARCH64 address size
Enable StandaloneMmMemLib to use longer physical addresses than 36 bits.
According to ARM "Learn the architecture - AArch64 memory management"
since Armv8.2-A physical address size was extended to 52 bits.
