Octeon II CPUs can switch from Big Endian to Little Endian freely even in kernel/supervisor mode. These patches allow an EdgeRouterPro to boot in LE mode with no hardware modifications. They have not been subjected to extensive testing yet and should be considered experimental. (I have seen some strange memory corruption in libstdc++ which I haven't yet been able to trace.) Parts of this patchset are based on the "GPL" sources released by Ubiquiti.
