From 79e436cad3b4a7db88408c3f05175028f30d700d Mon Sep 17 00:00:00 2001 From: Becky Bruce Date: Wed, 3 Dec 2008 22:36:26 -0600 Subject: sbc8641d: Fix PCI mapping concepts Rename _BASE to _BUS, as it's actually a PCI bus address, separate virtual and physical addresses into _VIRT and _PHYS, and use each appopriately. This makes the code easier to read and understand, and facilitates mapping changes going forward.
