| /** @file | |
| The EFI_SMM_SWAP_ADDRESS_RANGE_PROTOCOL is related to EDK II-specific implementation | |
| and used to abstract the swap operation of boot block and backup block of FV in EFI | |
| SMM environment. This swap is especially needed when updating the boot block of FV. | |
| If a power failure happens during the boot block update, the swapped backup block | |
| (now the boot block) can boot the machine with the old boot block backed up in it. | |
| The swap operation is platform dependent, so other protocols such as SMM FTW (Fault | |
| Tolerant Write) should use this protocol instead of handling hardware directly. | |
