The name of this board is Armadillo-9. Atmark Techno Inc in Japan
developed it. Product and distributer information is written by the
following link.

Yes, I think epe.c is MI. I am setting the MAC address in platform
depended code.

Linux runs on Armadillo-9, and that source code is attached to a
product.
I did not work it with a same value as TS-7200, so I set MDCDIV value
written in linux.
