Sascha,

actually I forgot to mention that using a separated mdio driver requires
it to be probed before the eth driver. Right now, this is implicity
done by reordering the Makefile accordingly.

This may be fine for now, but I guess there may be some issues in the
future. Have you thought about deferred probing for barebox, too?
