 1.4  07-Sep-2015  dholland Final bit of PR 41200: headers that declare ioctls should include sys/ioccom.h.
This covers most if not all of the MD headers.

XXX: a lot of the ioctl definitions in some of these files are cutpasted.
 1.3  08-Feb-2011  rmind branches: 1.3.14; 1.3.32;
Remove clause 3 (UCB advertising clause) from the University of Utah
copyright. Confirmed by Mike Hibler, mike at cs.utah.edu - thanks!
Also, merge UCB and Utah copyright texts back into one, as they
originally were.

Extra verification by snj@.
 1.2  17-Oct-2007  garbled branches: 1.2.2; 1.2.4; 1.2.8; 1.2.48; 1.2.54; 1.2.56;
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.
 1.1  21-Jun-2007  garbled branches: 1.1.2; 1.1.6; 1.1.8; 1.1.10;
file grfioctl.h was initially added on branch ppcoea-renovation.

 1.1.6.1  26-Oct-2007  joerg Sync with HEAD.

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.
 1.1.2.1  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.
