I'm still hoping, but so far it seems most people have got better things
to do, and of those that do have an opinion the balance is slightly
positive.

So here's a first cut of a patch to add the new names. I've not touched
of_platform because that is supposed to go away. That will lead to some
odd looking code in the interim, but I think is the right approach.

Most of these are straight renames, but some have changed more
substantially. The routines for the flat tree have all become fdt_foo().
I'd be inclined to drop "early_init" from them too, because they're
basically all about early init, but Grant said he'd prefer not to I
think. I've also renamed the flat tree tag constants to match libfdt.

I've left for_each_child_of_node(), because I read it as "of", but maybe
it's "OF"?

cheers
