ACK. :-( I'm surprised to see so much push-back on what looks like a
simple piece of information here.

I've had users *specifically* asking for this kind of identification
so that they can verify the version of the DTB they're using at
runtime. Right now it can be a guessing game, which does not help
people trying to debug problems.

Cheers,
