I was also looking at using the OF code on m68k, but for a different
reason. My goal was to get macio_bus working so we can merge a few
of the m68k Mac drivers into the ppc Mac drivers. The simplest way
to do that seemed to be supporting OF since macio_dev is a wrapper
for of_device. It was also a nice way to build up a table of all the
onboard devices in memory. Hopefully it would enable better user-space
device detection as well.
I got the framework built against an older kernel, but it wasn't enough
to be useful at that point. This set of patches could help quite a bit.
