not sure i follow ... what do you propose changing ? easylogo can be changed to use this (a few Blackfin boards) because atm, compression support with that is implemented by running `gzip`. this is because i wasnt able to figure out how to get the decompression routines in u- boot to play with a zlib compressed stream (i.e. no gzip header). -mike
