It's *always* a small amound of code, at a start. Then we get
floppy disk drivers and the tty layer. ;-)

If I wasn't a PPC/OF guy to some degree, I'd hate PPC/OF people
for bringing arch-specific details into a generic code... :-P

No matter how small the OF code is, I believe we shouldn't put it
into the generic code. Take a look at mmc_spi case again, it can be
easily extended to any arch, because there is no arch-specific stuff,
but a "get/put" pattern for platform data.

Thanks,
