There isn't really a general plan, someone just needed to get around
to assembling the patch.  I just sent out a patch which updates the
in-kernel dtc and libfdt to 1.2.

Longer term, once microblaze support goes into mainline, we probably
should move the in-kernel copy to scripts/ and/or lib/ so that powerpc
and microblaze can share it.

It would be nice to have some better automagical way of pulling the
dtc git tree into a kernel git tree, but I haven't gotten my heard
around the gittery involved.  There's a bit more to it than simply
importing the dtc tree verbatim into the kernel tree - the pulls from
upstream would need to be co-ordinated in some cases with updates to
the in-kernel makefiles, libfdt_env.h and users of dtc and libfdt.
