add lzop decompression support
Add lzop decompression support to the existing lzo bitstream handling (think gzip versus zlib), and support it for uImage decompression if CONFIG_LZO is enabled. Lzop doesn't compress as good as gzip (~10% worse), but decompression is very fast (~0.7s faster here on a slow ppc). The lzop decompression code is based on Albin Tonnerre's recent ARM Linux lzo support patch. Cc: albin.tonnerre@free-electrons.com Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
