In order to support both indirect PCI configuration space access as well as direct-mapped PCI configuration space access (such as implemented on the IBM 27-82650 PCI Host Bridge), switch to a function vector based PCI configuration space access implementation. The appropriate PCI chipset tag is provided by platform-specific code.

Prep super-commit: 1) create new pnpbus psuedo bus. This is a bus layer that reads the PNP tree from the residual data and allows attachment of devices with the information given therein. Based loosely on i386/pnpbios. 2) Delete obio bus, as with the pnp bus we no longer need it. 3) Create a number of functions that gather the information needed to set up the machine from the residual data, rather than hardcoding it in. 4) Create a quirk table for machines that are bizzare enough that the residual information is not sufficient. (such as the 6015) 5) Using the data gathering routines and the quirk table, delete struct platform completely from the architecture. Prep is now almost completely dynamic in figuring out the machine it is running on and setting things up properly. 6) Add a wdc_pnpbus driver which attaches the wdc controller found on some 7248's and the 6015. This replaces the now-defunct wdc_obio. 7) delete all the mot_* and ibm_* files, and replace them with a single ibm_machdep.c which only contains the quirk functions for the 6015 and the 6050. 8) Modify GENERIC to work with all this stuff.

Completely rework how we look up PCI interrupts on prep: 1) Rather than build an array of the pci->intr mappings, build a proplib tree. 2) add a SIMPLEQ of device properties to the pci_chipset_tag to hold the proplib trees of each bus. 3) Move the interrupt routing code from pci_conf_interrupt to pci_map_intr() 4) Deal properly with non-native PCI bridge chips that are not recognized by the prep firmware, and therefore are not noted in the residual data. The major win of this restructure is #4. Hopefully I haven't broken anything. Tested on a 7248-100, 7043-140 and 7024-E20.

General fixups: 1) Fix support for the powerstack E1. This machine needs to use the 8259 directly, and cannot use the prep interrupt vector register. Place a quirk entry in the table for the machine. 2) Add a new com0_vreset boot image. The vreset code only works on a few machines, and breaks others like the 7025-F40. Its only limitedly useful when used with the com0, so just make it an optional image the user can install by hand if they want. 3) Bump the bootloader to 1.8 with the above change.

Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
