+ Class_PIEnable[2]: Update PEI core to only consume EFI_PEI_FIRMWARE_VOLUME_INFO_PPI
+
+ Code Change :
+ 1) Update PEI core to consume EFI_PEI_FIRMWARE_VOLUME_INFO_PPI to get the location of new FVs other than BFV
+ reported by PEIMs .
+
+ Possible Impacts:
+ 1) Platform code that is going to inform PEI core about the new FVs other than BFV should install
+ EFI_PEI_FIRMWARE_VOLUME_INFO_PPI. A library function named PeiPiLibBuildPiFvInfoPpi() defined in
+ MdePkg\Include\Library\PeiPiLib.h can be used to install the PPI.
+ There are two notes worth mentioning:
+ 1) Platform PEIMs should report at least FVs containing DXE_CORE and all other PEIM to PEI Core if they
+ are not in the BFV.
+ 2) PEI core will dispatch PEIMs in the FV reported by PeiPiLibBuildPiFvInfoPpi() and invoke BuildFvHob () to build the
+ FV HOB for this FV (see Section 4.8.1.2 of Vol 1 named Multiple Firmware Volume Support for details).
+ If PEIM only want to inform DXE core about the existance of the new FV, it should call BuildFvHob instead.
+
+
+ Class_PIEnable[3]: Update PEI core to support RegisterForShadow feature introduced by PI spec
+
+ Code Change :
+ 1) DXEIPL no longer produce EFI_PEI_FV_FILE_LOADER_PPI defined in Framework PEI CIS.
+
+ Possible Impacts:
+
+ 1)All PEIMs that need to shadow itself into memory and rerun the entry point should be updated to call RegisterForShadow
+ (PeiServicesLibRegisterForShadow () is a helper function).
+ 2)The depex of PEIMs that including EFI_PEI_FV_FILE_LOADER_PPI (or gEfiPeiFvFileLoaderPpiGuid) should be removed.
+
+
+ Class_PIEnable[4]: Update PEI core to produce other new features defined in PI spec
+
+ Code Change :
+ 1) Add the following services: FfsGetFileInfo, FfsFindFileByName and FfsGetVolumeInfo
+
+ Possible Impacts:
+
+ 1) Platform code is recommended to make use of these new PI features. The functions in MdePkg/Include/Library/PeiServicesLib.h are
+ recommended as PeiServices is saved for every PEI Services API invokation.
