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.
