I think having both options would be a good idea.  It would also be
nice to have options to do this from the dts file (something similar
to /memreserve/).

Ok.  How would you envisage this working?

I've thought for some time that it would be a good idea to add an
"info" output mode.  In that mode instead of outputting a converted
device tree, it would give various bits of info on the input tree.
This would include things like the header field debugging information
that's currently output as pseudo-error messages when using dtb input.

I'm not sure to what extent your "--stats" idea would overlap with
that.
