>Subject: [RFC] [patch] Merge
>MdeModulePkg\BaseTianoCustomDecompressLib into
>MdePkg\BaseUefiDecompressLib
>
>BaseUefiDecompressLib in MdePkg implements the UEFI Decompress
>algorithm.
>BaseUefiTianoCustomDecompressLib in MdeModulePkg implements the UEFI
>Decompress algorithm
>and Tiano Custom Decompression algorithm.
>Tiano custom decompression algorithm shares most of the code with the UEFI
>Decompress algorithm.
>So BaseUefiDecompressLib and BaseUefiTianoCustomDecompressLib have
>lots common code.
>We plan to merge the MdeModulePkg\BaseTianoCustomDecompressLib into
>MdePkg\BaseUefiDecompressLib,
>in order to reduce the duplicated codes and maintain these two Decompress
>algorithms easily.
>
>Propose to update:
>1. Make the implemtations of these two Decompress algorithms in exstring
>MdePkg/Library/BaseUefiDecompressLib.
>2. keep existing BaseUefiDecompressLib.inf in
>MdePkg/Library/BaseUefiDecompressLib for UEFI Decompress algorithm.
>3. Add BaseTianoCustomDecompressLib.inf in
>MdePkg/Library/BaseUefiDecompressLib for Tiano Custom Decompression
>algorithm.
>4. Make existing BaseUefiDecompressLib.c in
>MdePkg/Library/BaseUefiDecompressLib to support the Tiano Custom
>Decompression algorithm
> besides existing UEFI Decompress algorithm.
>5. Remove the gTianoCustomDecompressGuid header file from
>MdeModulePkg/Include/Guid/TianoDecompress.h
> Move the gTianoCustomDecompressGuid definition from
>MdeModulePkg.dec to MdePkg.dec.
>6. Remove the MdeModulePkg/Library/BaseUefiTianoCustomDecompressLib
>from edk2.
>
>The draf updates are covered by this patch.
>
>Impact analysis:
>1. No impact to the usage of BaseUefiDecompressLib.
>2. Need to update the consumers of
>
>MdeModulePkg/Library/BaseUefiTianoCustomDecompressLib/BaseUefiTiano
>CustomDecompressLib.inf
> to use
>
>MdePkg/Library/BaseUefiDecompressLib/BaseTianoCustomDecompressLib.in
>f
>3. Current impacted platforms:
> edk2 repo:
> Nt32Pkg
> Quark
> vlv2tbltdevicepkg
> edk2-platforms repo:
> AMD Overdrive
> Lemaker Cello
> Raspberry Pi3
> SoftIron 1000
> D03/D05/D06
> Hikey/Hikey960
>
>For platforms in edk2 repo, we can add the
>BaseTianoCustomDecompressLib.inf in
>MdePkg/Library/BaseUefiDecompressLib firstly
>and then update platform consumers, remove the
>MdeModulePkg/Library/BaseUefiTianoCustomDecompressLib at last.
>
>For the platforms in edk2-platforms repo, I find they don't use the Tiano
>Custom Decompression algorithm actually.
>So we can update them to use the
>MdePkg/Library/BaseUefiDecompressLib/BaseUefiDecompressLib.inf firstly
>to avoid any
>imconpatible changes.
