EfiCompress and TianoCompress are all originated from LZ77 algorithms and they have very little different, that different position set for Huffman code. EfiCompress is defined in EFI 1.1 spec and EfiRom tool need it to create a recognized compressed EFI driver. TianoCompress is for pursuer more size saving and it used be GenFfs and GenSection tools. So this patch: 1) Split EfiComress and TianoCompress in edkII’s tools 2) Change EfiRom tool use EfiCompress and GenFfs/GenSection use TianoCompress git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@2064 6f19259b-4bc3-4df7-8a09-765794883524
