I am not talking about the ePAPR flat tree.  I am talking about the
flat tree as used in PowerPC Linux for many years now.

It's also well-proven technology.  And lastly, wouldn't it be nice if
we could hand-off the DTB to the kernel at boot -- bye-bye legacy
interfaces.

You'll always have to write some of it by hand, in one form or another,
for some system-specific devices that cannot be probed or that you don't
want to probe for (PHBs, I/O bridges, ...)
