But how else would you do it? If we wanted to suport direct
configuration of i2c devices on sparc64 like on macppc, we would need
to add a, say, si2c bus to sparc64. Just like ki2c on macppc. Thus
resulting in a specialized, sparc64 MD si2c bus attachment.

Or do you mean: Add a MI directly configured i2c bus, say di2c and
argument it by a single MD scan function? (As firmware scanning is
inherently MD.)

Maybe you could provide an example implementation for sparc64 to
clearify things.
