I haven't followed this discussion at all, so here's a question.

What does this mean for the _installed_ dtb files? Do they move
location? If they do, lots is going to break, because there will
be u-boot configurations and other scripts that assume the flat
directory structure for the installed dtb files.

I don't think changing the installed dtb structure is acceptable
at this point in time. It's something that _should_ have been
thought about when ARM was converted to dtb, it's too late to be
changing that now.
