Hi Kumar,

Thanks for working on this.  I cleaned up my u-boot-fdt subrepo in 
preparation for the next round of improvements, of which this will be 
the base.

I've been thinking about how best to do the unfork libfdt and how best 
to stay in sync down the road, but I don't have any good ideas other 
than to just do it.  Down the road, we could try to cherrypick just the 
libfdt changes (assuming David and Jon keep libfdt changes distinct from 
dtc changes in their patches), or we can have an Project Orion approach: 
lots of big bangs.

FWIIW, I thought about doing our unfork via applying libfdt patches from 
the dtc repository - according to my README, I started from commit
   857f54e79f74429af20c2b5ecc00ee98af6a3b8b
which is in there.  Hmmmmm, something to think about.  That would help 
with the size of the patch (one Project Orion patch or a bunch of 
smaller ones), it would be nice for tracking who changed what and why, 
but it will be a fair amount of work (and some scripting) to identify 
the applicable libfdt patches.
