These days, the macio bus is a real device-model bus. The code still
lives in drivers/macintosh, but it will be used by more than just
pmac machines whenever I get the 68k mac support finished. It seems
like we really should have an include/linux/macio.h, and make the
whole thing act more like a normal bus. I would like to abstract out
more of it anyway, particularly the DMA support. That way we wouldn't
have several different drivers for the same chip due to bus interface
differences (see mace.c and macmace.c for an example of current practice).
This would eliminate at least macio.h and dbdma.h. Hopefully it would
get most of the mac specific code organized in a more logical fashion.
Any comments/requirements/suggestions?
