 1.18  21-Nov-2018  macallan further de-cargocult the new mmap() methods
 1.17  21-Nov-2018  thorpej EINVAL (22) is a valid return value for ARM mmap routines; we need to
return -1 for invalid mmap attempts.
 1.16  18-Nov-2018  macallan - support *_mmap()
- support BUS_SPACE_MAP_PREFETCHABLE for memory spaces
- fill in *_stream methods if needed
With this Xorg with wsfb works on iyonix. The nv driver still crashes ( and
needs options INSECURE ), something seems to be wrong with accessing IO space.
But, progress.
 1.15  16-Mar-2018  ryo branches: 1.15.2;
use designated initializer to make adaptability and flexibility for changing struct bus_space.
no functional change.
 1.14  02-Mar-2014  joerg branches: 1.14.28;
Skip a tautologic check if we know it is one.
 1.13  01-Jul-2011  dyoung branches: 1.13.2; 1.13.12; 1.13.16;
#include <sys/bus.h> instead of <machine/bus.h>.
 1.12  24-Feb-2010  skrll Typo in comment.
 1.11  17-Oct-2007  garbled branches: 1.11.20; 1.11.40;
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.
 1.10  12-May-2007  gavan branches: 1.10.10; 1.10.12;
Implement ATU Direct Window in order to increase available PCI address
space.
 1.9  24-Nov-2005  yamt branches: 1.9.26; 1.9.30; 1.9.32; 1.9.38;
bus_dmamem_map: honour BUS_DMA_NOWAIT. noted by Manuel Bouyer.
bus_space_map: always do NOWAIT allocation as it used to be before yamt-km.

we have too many copies!
 1.8  01-Apr-2005  yamt branches: 1.8.2; 1.8.8;
merge yamt-km branch.
- don't use managed mappings/backing objects for wired memory allocations.
save some resources like pv_entry. also fix (most of) PR/27030.
- simplify kernel memory management API.
- simplify pmap bootstrap of some ports.
- some related cleanups.
