eth0.ethaddr=80:81:...

I removed the MAC addresses from the default environments since it was a
very bad idea.

NAND support (including booting from NAND) has been tested on the
phycore i.MX27 module. So the NAND driver inself is in place, only the
board specific bits are missing. You can use board/pcm038 as a template.
