 * Sun4u S-bus definitions.  Here's where we deal w/the machine
 * dependencies of sysio.
 *
 * SYSIO implements or is the interface to several things:  
 *
 * o The SBUS interface itself
 * o The IOMMU
 * o The DVMA units
 * o The interrupt controller
 * o The counter/timers
 *
 * Since it has registers to control lots of different things
 * as well as several on-board SBUS devices and external SBUS
 * slots scattered throughout its address space, it's a pain.
 *
 * One good point, however, is that all registers are 64-bit.
