In theory that shouldn't be too difficult, although there are a few
weirdnesses - just one example: macppc and sparc64 disagree about the
OF_interpret function - one uses OF_interpret(const char *, int, int,
...), the other uses OF_interpret(const char *, int, ... ), then there
are the obvious problems with 64bit vs 32bit ( although these are just
a matter of choosing the correct data type ). macppc does some voodoo
to make the framebuffer cacheable, I don't think it would work the same
way on sparc64.
The other OF calls are exactly the same.
With a little fiddling it could probably talk to SBus framebuffers too,
the only reason it attaches to pci is that it does so on macppc.
have fun
