Mon May 13 15:08:56 UTC 2019
Dandan:
UefiTianoDecompress() API function header doesn't describe the parameter Version and the assert condition when Version is not 1 or 2. Please update the function comments in header file and C source file.
With this change, Reviewed-by: Liming Gao <liming.gao at intel.com>
Thanks

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

> We plan to merge the BaseUefiTianoCustomDecompressLib

> 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.
