jmallett 4948f4b8d5 Import the Cavium Simple Executive from the Cavium Octeon SDK. The Simple
Executive is a library that can be used by standalone applications and kernels
to abstract access to Octeon SoC and board-specific hardware and facilities.
The FreeBSD port to Octeon will be updated to use this where possible.
