+EDK_3983: Non-Compatible: lgao4
+
+ Class_Library: Remove CustomDecompressLib library class.
+
+ Code Change:
+ 1) Remove the definition MdePkg\Include\Library\CustomDecompressLib.h and
+ library instance MdePkg\Library\BaseCustomDecompressLibNull for CustomDecompressLib.
+
+ Possible Impacts:
+ 1) Drivers don't use this library class any longer. But they can use new ExtractGuidedSectionLib
+ library class to extract the compressed guided section data.
+ 2) The instance of CustomDecompressLib should be changed to register the decode function
+ into ExtractGuidedSectionHandler list, and not to produce CustomDecompressLib class.
+ 3) Platform.dsc file doesn't use this library instance any longer.
+==========================================================================================
+EDK_3980: Non-Compatible: lgao4
+
+ Class_Library: Add ExtractGuidedSectionLib library class to replace CustomDecompressLib.
+
+ Code Change:
+ 1) Add the definition MdePkg\Include\Library\ExtractGuidedSectionLib.h and
+ library instance MdePkg\Library\PeiDxeExtractGuidedSectionLib for new ExtractGuidedSectionLib.
+ 2) Add gEfiMdePkgTokenSpaceGuid.PcdMaximumGuidedExtractHandler in MdePkg, which is used by
+ PeiDxeExtractGuidedSectionLib library instance.
+ 3) Update DxeIpl and DxeMain modules of MdeModulePkg to use new ExtractGuidedSectionLib library class.
+ 4) Update BaseUefiTianoCustomDecompressLib of IntelFrameworkModulePkg not to produce CustomDecompressLib,
+ and to register TianoDecomress handler into ExtractGuidedSectionHandler list.
+
+ Possible Impacts:
+ 1) Platform.dsc file should update library instance and PCD if it contains DxeIpl and DxeMain modules.
+ It should use MdePkg\Library\PeiDxeExtractGuidedSectionLib library instance and
+ set gEfiMdePkgTokenSpaceGuid.PcdMaximumGuidedExtractHandler PCD value.
