-- Add BootLoaderTolumSize support -- Extend FspApiCallingCheck with ApiParam for BootLoaderTolumSize -- Rename all Bootloader to BootLoader as official name -- Rename Ucode to Microcode -- Remove FspSelfCheck API, because it is merged into SecPlatformInit -- Add GetFspVpdDataPointer() in FspCommonLib.h -- Document FspSecPlatformLib.h -- Reorg FSP_PLAT_DATA data structure to let it match FSP spec. -- Move helper function in FspSecCore to reduce platform enabling effort -- Fix LibraryClasses declaration in DEC file. -- Enhance PatchFv to check if it is valid FSP bin.
