Don't get me wrong. I want mv643xx_eth DT or even platform_data to
evolve to a fully self configured driver not depending on proper u-boot
setup at all.

But I don't want to go that road now and I wonder if it might be safer
for us (and PPC guys) if we start mv643xx_eth over from scratch one day.

For this patch set, I want a basic DT binding that works. Patching the
driver to play with kirkwood loosing the MAC and other important
registers is not my main concern here. If clearing that one bit doesn't
help for all kirkwood boards, I'd rather leave the non-gating
workaround.

mv643xx_eth not knowing DT for ARM is stalling last important bits for
Orion SoCs. I want this to go in first as with David another maintainer
is involved.
