What's in a name.. we don't have a sun4{d,m,u} port yet, so there's no
telling for sure there's going to be an "obio". The name is likely to be
adopted though since it's conveniently congruent to Sun's device
representation in their PROMs. If there's no precedent (cf. the on-board
devices on sun4c's) something has to be invented -- like "mainbus" -- as
the original author of the sparc port has done.
