I have not compiled DTB with kernel!!! This not make sense. This was the first
thing which I removed some month ago.
I registered discussion about incorporating DTB to bitstream. It's bogus because
if you do it, you can't change any parameters. If you want to DTB in your
design, you can add xps_bram (or whatever) to your design and you can load DTB
with bitstream.
