9 new interfaces and how they are used to write an SBUS device driver.
28 	Here is how probing is performed by an SBUS driver
63 into an initialized state, etc.
67 	Each SBUS device structure contains an array of descriptors
77 	The mapping information is stored in an opaque value
78 typed as an "unsigned long".  This is the type of the return value
105 	Second argument to sbus_ioremap is an offset for
146 	Or perhaps there is a data port register at an offset of
170 		Whatever it is, it's an implementation detail.  The
184 consistent with a view of a device. Think of it as an uncached memory.
194 2. a device does DVMA accesses, then posts an interrupt;
215 done with an sbus_writel() into some device register.
246 	There is an equivalent set of functions doing the same thing
270 	This one uses result of sbus_ioremap as if it is an address.
