+  Class_ModuleRemove[0]:  Remove AtapiPassThru module from MdeModulePkg.  AtapiPassThru\r
+      module is only used for testing. We already have a driver in OptionRomPkg to\r
+      produce ScsiPassThru and ExtScsiPassThru based on PCD setting. We can remove it\r
+      from MdeModulePkg.\r

 \r
 \r

+      Code Change :\r
+      1) Remove module MdeModulePkg/Bus/Pci/AtapiPassThruDxe/AtapiPassThru.inf \r

 \r
 \r

+      Impact to platform code:\r
+      If a platform happens to refer to this module in their dsc file, please use the\r
+      counterpart module in OptionRomPkg.\r

-         Class_PIEnable[0]:  Enable DXE Core to produce EFI_FIRMWARE_VOLUME2_PROTOCOL only.\r
+      Code Change :\r
+      1) MdeModulePkg/Core/Pei/FwVol/FwVol.c \r
+      \r
+      Impact to platform code:\r
+      1) If platform module want to inform both PEI core and DXE core about the existance of new FV \r
+         it must both install EFI_PEI_FIRMWARE_VOLUME_INFO_PPI and FV HOB. \r
+\r
+          A example is given belows:\r
+    \r
+            PiLibInstallFvInfoPpi (\r
+              NULL,\r

+              (UINT32) FvHeader->FvLength\r
+              );\r
+\r
+            PEI core does not automatically build FV HOB upon notification of a EFI_PEI_FIRMWARE_VOLUME_INFO_PPI. \r
+            The description in Item 2 in Section 4.8.1.2 in Vol 1 of PI spec will be updated to remove the \r
+            "Create a new firmware volume HOB" wording.\r
