Looks nice to me. There's a patch below to add the GEM stuff to the
binding too if you want to role that in.

Yes, I will push it in a "v3" (I was busy correcting a bug and did not see your answer before sending v2...).

BTW, I think we may also modify the MII/RMII selection code for adding gigabit selection... but maybe you already have the patches?
