This is an experimental patch set for enabling Little Endian working on the Cavium Octeon II. It may work for other Octeon models but has not been tested on them. It's been extensively tested on a Ubiquiti EdgeRouter Pro, building a current GNU/Linux toolchain from sources using an external USB drive. My contributions (with the exception of the changes to octeon-md5) are mainly cherry-picked from the GPL tarball released by Ubiquiti, and appear to have originally been authored by Cavium.
