+ Class_PIEnable[1]: Add PeiPiLib library class and replace PiLib with DxePiLib library class.
+
+ Code Change :
+ 1) Change MdePkg/Include/Library/PiLib.h to MdePkg/Include/Library/DxePiLib.h. DxePiLib is mainly used
+ for modules in DXE phase. Add a DxePiLib.h library instance at MdePkg/Library/DxePiLib/DxePiLib.inf.
+ 2) Add MdePkg/Include/Library/PeiPiLib.h. PeiPiLib is mainly used by modules in PEI phase.
+ Add a DxePiLib.h library instance at MdePkg/Library/PeiPiLib/PeiPiLib.inf.
+ 3) Rename API in PeiPiLib.h from PeiPiLibBuildPiFvInfoPpi to PiLibInstallFvInfoPpi.
+ 4) Rename APIs originally in PiLib.h with new names defined in DxePiLib.h:
+ 4.1) GetSectionFrom*Fv functions are changed to PiLibGetSectionFrom*Fv to reduce possibility of name collision.
+ 4.2) Remove API named ImageHandleToFvHandle and GetSectionFromFvFile
+
+
+ Possible Impacts:
+
+ 1) Platform modules that reference PeiPiLibBuildPiFvInfoPpi and GetSectionFrom*Fv should reference the new
+ names defined.
+ 2) Platform DSC file that specifying library instance for PiLib should be updated to add one line (a example
+ is given below):
+ [LibraryClasses.common.DXE_DRIVER]
+ ...
+ DxePiLib|MdePkg/Library/DxePiLib/DxePiLib.inf
+ ...
+ 3) Platform DSC file including modules that make use of API from PeiPiLib.h should add the following line (a example
+ is given below):
+ [LibraryClasses.common.PEIM]
+ ...
+ PeiPiLib|MdePkg/Library/PeiPiLib/PeiPiLib.inf
+ ...
+
