Hi Gregory

First off, the indentation looks wrong. Might be a space/tab issue.

I would also be tempted to place this code into board-dt.c and not
touch or even compile rd78x00-masa-setup.c when using DT. If i
remember correctly, Jason had a patch for Kirkwood which centralized
all the ethernet setup code. You can maybe copy/paste that.
