The 21*4882a593Smuzhiyundo_bootm() function uses the lzmaBuffToBuffDecopress() function to expand the 22*4882a593Smuzhiyuncompressed image. 23*4882a593Smuzhiyun 24*4882a593SmuzhiyunThe directory U-BOOT/include/lzma contains stubs files that permit to use the 25*4882a593Smuzhiyunlibrary directly from U-BOOT code without touching the original LZMA SDK's 26*4882a593Smuzhiyunfiles. 27*4882a593Smuzhiyun 28*4882a593SmuzhiyunLuigi 'Comio' Mantellini <luigi.mantellini@idf-hit.com> 29
