pk be7f5a7031 Switch to a bus_space(9)-based device attachment scheme. 
The dma & lebuffer devices behave like busses to accommodate the
OBP layout. For practical purposes, they are implemented as
Sbus "extensions".
 1998-03-21 20:23:09 +00:00
pk 69fe6f242f Account for changed bus attachment scheme. 1998-03-21 20:11:30 +00:00
pk 165120cfaf Sbus attach arguments and map function prototypes go here. 1998-03-21 20:10:07 +00:00
pk 77f499595c 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.

pk 8a5023e38c After writing to the IOMMU flush registers, read something back from

This avoids utter lossage on some machines (SS4s & SS5s) where our caller
would see some of its local (`%lx') registers trashed. This is probably
caused by a silicon bug allowing interference on internal data paths..
