I suggest going with option 1. U-Boot supports several algorithms so another one is pretty easy to add. The last one was IH_COMP_LZ4, so you can search for that in the code. The commit was: 027b728d Add support for LZ4 decompression algorithm Regards, Simon _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
