These comments aren't relevant to the problems you're seeing, but
they're a good idea for writing device trees in general.

First, you may want to consider moving to the version 1 dts format
which uses C-style integer values throughout, instead of hex by
default.

device_type shouldn't be included here.

The binding for gianfar mdio and ethernet devices has been updated to
better fit conventions for use of device_type and compatible
properties.  Check booting-without-of.txt for the details.

Can someone from freescale please go though and update the existing
device trees, so that people stop copying the old crap.

And since this is a new port, you ought to be able to use a recent
u-boot and drop this backwards compatibility property.
