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.

branches: 1.12.30; 1.12.38; 1.12.48; 1.12.50; 1.12.52; 1.12.54;
merge ktrace-lwp.

branches: 1.11.12;
remove now unnecessary "pci_enumerate_bus" definitions

branches: 1.10.10;
Let machine-dependent code specify how to enumerate the bus.
Currently, everyone uses pci_enumerate_bus_generic().

branches: 1.9.2; 1.9.8;
Change bebox port to use the include MPC6XX files and the new common bus.h
framework.

branches: 1.8.2;
Define a pci_bus_dma_tag.

Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

Implement the more flexiable `evcnt' interface as discussed (briefly) on
tech-kern and now documented in evcnt(9).

kill __P in these files. (I had to look at them anyway with an eye for
adding some protos... and adding them with __P seems wrong, but mixing
__P and not __P in the same file seems wrong too, so...)

branches: 1.4.8; 1.4.16;
Moved from arch/bebox/pci/pci_machdep.h,v

vm_offset_t --> [pv]addr_t.

Make copyright notices with my name consistent.

Initial commit of NetBSD/bebox port.
