About FreeBSD support one more mini-pc

[Weiß, Jürgen]

I just updated u-boot sources and added CONFIG_CMD_ELF. I used
unmodified ubldr and unmodified FreeBSD WANDBOARD-DUAL. bootelf disables
L1 dcache as well.

I finally downloaded ubldr and used go to start the image. Now the FreeBSD
kernel fails to boot!
