+       Class_PIEnable[1]: Use new entry point for PeiCore defined in PI specification.\r
+       \r
+       Code Change:\r
+       1) Remove the definition and library instance for OldPeiCoreEntryPoinLib\r
+       \r
+       Possible Impacts:\r
+       1) Platform should select MdePkg/Library/PeiCoreEntryPoint/PeiCoreEntryPoint.inf for \r
+          PeiMain module.\r
+       2) The SecCore module should provide parameters for new entry point defined in \r
+          MdePkg\Include\Library\PeiCoreEntryPoint.h\r

+  Class_PIEnable[0]:  Update PeiServicesLib based on new features defined in PI spec.\r
+\r
+      Code Change :\r
+      1) Add the following services:PeiServicesRegisterForShadow, PeiServicesFfsGetFileInfo, PeiServicesFfsFindFileByName and PeiServicesFfsGetVolumeInfo\r
+      2) The paramter list of these functiuon has also been updated to replace EFI_FIRMWARE_VOLUME_HEADER to EFI_PEI_FV_HANDLE and EFI_FFS_FILE_HEADER\r
+         to EFI_PEI_FILE_HANDLE.\r
+      3) Add CONST to parameter of PeiServices EFI_PEI_SERVICES.EFI_PEI_RESET_SYSTEM\r
+\r
+      Possible Impacts:\r
+\r
+      1) Platform code should be updated to make use of these new PI features. The functions in MdePkg/Include/Library/PeiServicesLib.h are \r
+         recommended as PeiServices is saved for every PEI Services API invokation.\r
+      2) Now PEIM entry point is upadted to pass in PeiServices in type of (CONST EFI_PEI_SERVICS **). Platform code should be updated to \r
+         add (EFI_PEI_SERVICS **) cast to PeiServices before passing it to the previously defined PPI interface which needs a (EFI_PEI_SERVICS **)\r
+         type for PeiServices parameter.\r
+      3) The newly defined PPI should not inlcude PeiSevices in the paramter list as PI spec has standard way to retrive PeiServices (check VOL 1\r
+         Section 4.4 PEI Sevices Table Retrieval) for details. Beside, GetPeiServicesTablePointer() in MdePkg\Include\Library\PeiServicesTablePointerLib.h\r
+         also provide convinient way to retrieve the pointer to Pei Service Table.\r
