u-boot is what we support.  There's no other support in the codebase 
right now.  uboot gives us:

in a3 is passed in the cavium hardware descriptor.  All other registers 
are ignored on boot.  We only support version 6 and newer of the boot 
descriptor.  You can see the details of the structure in 
sys/mips/cavium/octeon_machdep.c starting with platform_start().
