With the changes below I managed to get your device tree port somewhat
working.
There are things missing though for a full device tree support. For
example, the GPIOs are not found. USB was not working, but I didn't test
if it works in a recent barebox without your patch. NAND wasn't found
also.
So, your work is a good start, but not yet enough to apply this patch.
