// The PI SMM memory attribute table contains the SMM memory map for SMM image.
//
// This table is installed to SMST as SMM configuration table.
//
// This table is published at gEfiSmmEndOfDxeProtocolGuid notification, because
// there should be no more SMM driver loaded after that. The EfiRuntimeServicesCode
// region should not be changed any more.
//
// This table is published, if and only if all SMM PE/COFF have aligned section
// as specified in UEFI specification Section 2.3. For example, IA32/X64 alignment is 4KiB.
//
// If this table is published, the EfiRuntimeServicesCode contains code only
// and it is EFI_MEMORY_RO; the EfiRuntimeServicesData contains data only
// and it is EFI_MEMORY_XP.
