Indeed, it was already pointed out by Emilio.

The fdt parsing code seem to be needing a ranges property, since it
prints a warning if it's not set.
For the reg one, honestly, I don't have a strong argument on this. The
platforms I'm used to did it that way, so did I. The documentation of
simple-bus doesn't seem to mention it, so maybe it's not needed at all.
I find it pretty convenient though to have the size and range where the
different IPs are located in.
