 1.6  20-Dec-2007  phx VT8231 IDE workaround for native mode with "compatibility" interrupts 14/15.
This time done right by calling pciide_machdep_compat_intr_establish() to
get a MD interrupt handler.
Verified that it compiles for XEN again.
 1.5  17-Oct-2007  garbled branches: 1.5.4; 1.5.8;
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.
 1.4  11-Dec-2005  christos branches: 1.4.30; 1.4.38; 1.4.48; 1.4.50; 1.4.52; 1.4.54;
merge ktrace-lwp.
 1.3  29-Jul-2004  drochner branches: 1.3.12;
remove now unnecessary "pci_enumerate_bus" definitions
 1.2  15-May-2002  thorpej branches: 1.2.10;
Let machine-dependent code specify how to enumerate the bus.
Currently, everyone uses pci_enumerate_bus_generic().
 1.1  29-Oct-2001  thorpej branches: 1.1.2; 1.1.4; 1.1.6;
Check in of work-in-progress of Firepower native device support.
We can find devices in PCI configuration space, but not much else.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.
 1.4.38.1  21-Jun-2007  garbled Completely rewrite ofppc from scratch.

1) Change it to be like the other ppc ports, and directly interface with
hardware, rather than trying to be slick and access everything through
the OFW. Instead, we gather configuration information from OFW, and use
that to discover hardware.

2) Change it over to powerpc bus_space and bus_dma.

3) Timecounters, generic soft interrupts.

4) Make use of the shared code in powerpc. (pic code, oea, bat code, etc)

5) Probably other stuff.. almost nothing remains of the original port.

It is assumed that in it's present state this will not run on any
machines. However, it should be pretty close, and will just need some
massaging and care from someone with access to hardware to make it work.
The code is written to target a CHRP compatible machine, but there is no
reason it cannot be ported to other machines like the Pegasos or Efika.
I simply don't have the knowledge of those machines to structure the code
for them, but I have attempted to keep it generic enough that such work
could still be done.

If anyone with access to hardware would like to take this on, I will
gladly assist as much as possible.
