EFI_SIGNATURE_16 -> SIGNATURE_16 EFI_SIGNATURE_32 -> SIGNATURE_32 EFI_SIGNATURE_64 -> SIGNATURE_64 EFI_FIELD_OFFSET -> OFFSET_OF EFI_MAX_BIT -> MAX_BIT EFI_MAX_ADDRESS -> MAX_ADDRESS These macros are not defined in UEFI spec. It makes more sense to use the equivalent macros in Base.h to avoid alias. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@7056 6f19259b-4bc3-4df7-8a09-765794883524
