    Add support for LZ4 decompression algorithm · 027b728d

    This patch adds support for LZ4-compressed FIT image contents. This
    algorithm has a slightly worse compression ration than LZO while being
    nearly twice as fast to decompress. When loading images from a fast
    storage medium this usually results in a boot time win.
    
    Sandbox-tested only since I don't have a U-Boot development system set
    up right now. The code was imported unchanged from coreboot where it's
    proven to work, though. I'm mostly interested in getting this recognized
    by mkImage for use in a downstream project.
