It's likely to be ugly no matter what, though I'll try to come up with 
something slightly nicer.  If I were doing this code from scratch, I'd 
probably liven the tree first and reflatten it to pass to the kernel.

Eh, probably not worth bothering doing an actual implementation at
this stage - I'll have to redo it for libfdt anyway.

Too late, I already wrote it -- it wasn't as bad as I thought it would
be.

flatdevtree uses some of the information it caches in the phandle
context stuff to remember who's the parent of a node.  libfdt uses raw
offsets into the structure, so the *only* way to implement
get_parent() is to rescan the dt from the beginning, keeping track of
parents until reaching the given node.

What is the benefit of doing it that way?
