We are currently maintaining a system out of tree that does exactly
this. Ill send patches shortly. We need to compare and converge
implementations.

We sent this to the mailing list about a year ago:

http://lists.gnu.org/archive/html/qemu-devel/2011-08/msg02953.html

We currently in an effort to make this machine independent, rather than
having to put dtb glue code in machine models.

Peter
