Cavium port

[alan yang]

I try to make rootfs on CF, with kernel that oeteon eval board u-boot
fatload could load the kernel, and bootoctlinux could boot FreeBSD
with root=CF device.  But it seems fatload needs msdos files system
type that I don't know how to create it under FreeBSD.

Wonder could shed some light how to work around to make CF card with
rootfs and kernel that would work.

Many thanks!
