Import Cavium's FreeBSD port, or the Octeon specific pieces, verbatim.
Yes, this puts things in the wrong place, doesn't compile and is woefully incomplete. However, it will allow us to more easily track against the upstream sources without needing to import the entire Cavium tree under vendor. This port is based on FreeBSD 7.0 as of April 2007 and the pre-import MIPS tree (aka mips2), so much work is necessary here.
