I'm not sure I understand the benefit of this - I thought the only parts of the device tree likely to get changed on the command line are the mac addresses and the chosen node's bootargs property, which today's u-boot handles well.

My belief is merely that the device tree data should belong in the u-boot image; they are both equally board specific.
