MdeModulePkg, MdePkg, NetworkPkg, OvmfPkg, PerformancePkg, ShellPkg: Library Migration.
Move libraries from ShellPkg into MdeModulePkg and MdePkg. The following libraries are being migrated out of ShellPkg in order to make their functionality more widely available. • PathLib: Incorporate into MdePkg/Library/BaseLib • FileHandleLib: MdePkg/Library/UefiFileHandleLib • BaseSortLib: MdeModulePkg/Library/BaseSortLib • UefiSortLib: MdeModulePkg/Library/UefiSortLib Diffs showing file changes are in the attached file, LibMigration.patch. A description of the changes follows: • Move ShellPkg/Include/Library/FileHandleLib.h to MdePkg/Include/Library/FileHandleLib.h • Move ShellPkg/Include/Library/SortLib.h to MdeModulePkg/Include/Library/SortLib.h • Move ShellPkg/Library/BaseSortLib to MdeModulePkg/Library/BaseSortLib • Move ShellPkg/Library/UefiSortLib to MdeModulePkg/Library/UefiSortLib • Move ShellPkg/Library/BasePathLib/BasePathLib.c to MdePkg/Library/BaseLib/FilePaths.c • Merge ShellPkg/Include/Library/PathLib.h into MdePkg/Include/Library/BaseLib.h • Delete ShellPkg/Library/BasePathLib; Includes BasePathLib.c and BasePathLib.inf • NetworkPkg/NetworkPkg.dsc • PerformancePkg.dsc • OvmfPkg/OvmfPkgX64.dsc • OvmfPkg/OvmfPkgIa32X64.dsc • OvmfPkg/OvmfPkgIa32.dsc o Update SortLib and FileHandleLib library classes to point to the new library locations. o Remove PathLib library class and make sure that BaseLib is described. • MdeModulePkg/MdeModulePkg.dec o Add SortLib library class • MdePkg/MdePkg.dec o Add FileHandleLib library class o Add PcdUefiFileHandleLibPrintBufferSize PCD • MdePkg/Library/BaseLib/BaseLib.inf o Add FilePaths.c to [Sources] • MdePkg/Include/Library/BaseLib.h o Update file description to include "file path functions" • ShellPkg/ShellPkg.dsc o Change PACKAGE_GUID to { C1014BB7-4092-43D4-984F-0738EB424DBF } o Update PACKAGE_VERSION to 1.0 o Update SortLib and FileHandleLib library classes to point to the new library locations. o Remove PathLib library class and make sure that BaseLib is described. o Remove ShellPkg/Library/UefiFileHandleLib/UefiFileHandleLib.inf from [Components] • ShellPkg/ShellPkg.dec o Update PLATFORM_VERSION to 1.0 o Remove declarations of the FileHandleLib, SortLib, and PathLib Library Classes o Update comment for the PcdShellPrintBufferSize PCD. • ShellPkg/Library/UefiShellLevel2CommandsLib/UefiShellLevel2CommandsLib.inf • ShellPkg/Application/Shell/Shell.inf o Remove PathLib from [LibraryClasses] • ShellPkg/Library/UefiShellLevel2CommandsLib/UefiShellLevel2CommandsLib.h • ShellPkg/Application/Shell/Shell.h o Remove #include <Library/PathLib.h> • ShellPkg/Library/UefiShellLevel1CommandsLib/UefiShellLevel1CommandsLib.inf o Add PathLib to [LibraryClasses] • ShellPkg/Library/UefiShellLevel1CommandsLib/If.c o Remove #include <Library/PathLib.h> • ShellPkg/Application/ShellSortTestApp/ShellSortTestApp.inf o Add MdeModulePkg/MdeModulePkg.dec to [Packages] • MdeModulePkg/Library/BaseSortLib/BaseSortLib.inf • MdeModulePkg/Library/UefiSortLib/UefiSortLib.inf o Replace ShellPkg.dec with MdeModulePkg.dec in [Packages] • MdeModulePkg/Library/UefiSortLib/UefiSortLib.c o Remove #include <ShellBase.h> o Define USL_FREE_NON_NULL() to replace SHELL_FREE_NON_NULL() Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Daryl McDaniel <daryl.mcdaniel@intel.com> Reviewed-by: Jaben Carsey <jaben.carsey@intel.com> Reviewed-by: Erik Bjorge <erik.c.bjorge@intel.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@16601 6f19259b-4bc3-4df7-8a09-765794883524
