[PATCH] powerpc: Add OF address parsing code (#2)
Parsing addresses extracted from Open Firmware isn't a simple matter. We have various bits of code that try to do it in various place, including some heuristics in prom.c that pre-parse addresses at boot and fill device-nodes "addrs", but those are dodgy at best and I want to deprecate them. So this patch introduces a new set of routines that should be capable of parsing most types of addresses and translating them into CPU physical addresses. It currently works for things on PCI busses and ISA busses and should work on "standard" busses like the root bus or the MacIO bus that don't put funky flags in addresses. If you have other bus types that do use funky flags, you'll have to add new bus type translators, which is fairly easy.
