[edk2-devel] [patch v2 1/3] MdePkg: Merge TianoCustomDecompress algorithm into

Dandan Bi dandan.bi at intel.com
Wed May 15 02:19:58 UTC 2019


REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1722

We plan to merge the BaseUefiTianoCustomDecompressLib
in MdeModulePkg into the BaseUefDecompressLib in MdePkg.
In order to reduce the duplicated codes and maintain
easily.
This patch adds a new fdf file in BaseUefDecompressLib
(BaseUefiTianoCustomDecompressLib.inf) to keep the same
functionality and usage model with the one in MdeModulePkg,
and then update consumer to use this new one one and
remove the one in MdeModulePkg finally.
