OK guys, here they come. Note that they're now simplified since the
eth* aliases have been added to the dts.

Marvell uses a specific atag in its u-boot which includes among other
information the MAC addresses for up to 4 network interfaces.

Works like a charm!  Thanks for sharing these.

It may be a while until an alternative to Marvell's uboot is available
for the Mirabox, so it's a shame these patches won't be making it into
the mainline kernel.

Ethan
