4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The EFI_SMM_SWAP_ADDRESS_RANGE_PROTOCOL is related to EDK II-specific implementation
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync and used to abstract the swap operation of boot block and backup block of FV in EFI
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync SMM environment. This swap is especially needed when updating the boot block of FV.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync If a power failure happens during the boot block update, the swapped backup block
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync (now the boot block) can boot the machine with the old boot block backed up in it.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The swap operation is platform dependent, so other protocols such as SMM FTW (Fault
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Tolerant Write) should use this protocol instead of handling hardware directly.
