+         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

+               Kodama
+               Hikari
+         Say Y here for most Octeon reference boards.
