jmallett cdfefa0ba0 Merge Cavium Octeon SDK 2.0 Simple Executive; this brings some fixes and new
facilities as well as support for the Octeon 2 family of SoCs.

XXX Note that with our antediluvian assembler, we can't support some Octeon 2
    instructions and fall back to using the old ones instead.
