// 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 | |
