Update of /cvsroot/src/sys/arch/sparc/dev
In directory nb00:/tmp/cvs-serv13166

Modified Files:
	obio.c sbus.c 
Log Message:
Switch to a bus_space(9)-based device attachment scheme.

	- device attachment arguments contain bus-specific
	  address and interrupt levels.

	- devices must call back on bus map functions to get their
	  addresses and interrupt levels translated properly.

	- sun4m's obio bus is treated like an Sbus slot.

	- the sun4-style obio bus has its own attach arguments
	  and map functions.
