Doug Rabson	21c3015a24	* Completely rewrite the alpha busspace to hide the implementation from ... the drivers. * Remove legacy inx/outx support from chipset and replace with macros which call busspace. * Rework pci config accesses to route through the pcib device instead of calling a MD function directly. With these changes it is possible to cleanly support machines which have more than one independantly numbered PCI busses. As a bonus, the new busspace implementation should be measurably faster than the old one.	2000-08-28 21:48:13 +00:00
