I think two DTS files is the best approach for now. A few of us had an idea to introduce
conditional statements in to the DTS, and U-Boot would examine the board and/or
environment variables and then apply the conditions to the device tree before booting the
kernel. This would allow you to merge the two DTS files into one, but we're quite a ways
off from implementing this feature. In the meantime, two DTS files is okay.
