This option supports all of the Octeon reference boards from Cavium
Networks. It builds a kernel that dynamically determines the Octeon
CPU type and supports all known board reference implementations.
Some of the supported boards are:
EBT3000
EBH3000
EBH3100
Thunder
Kodama
Hikari
Say Y here for most Octeon reference boards.
