- First stab at getting the ppc ports building and working.
- The sandpointx3+altimus has been consolidated into one directory for now. - Added support for having different versions of the pci access functions on a per bus basis if needed. Hopefully I have not broken something inadvertently. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1786 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
