8446b20662 Add an Open Firmware access module for real-mode OF accesses to the PowerPC
build. This is required for the IBM Mambo simulator, as well as a variety
of non-Apple PowerPC hardware.

1c96bdd146 Add support for 64-bit PowerPC CPUs operating in the 64-bit bridge mode
provided, for example, on the PowerPC 970 (G5), as well as on related CPUs
like the POWER3 and POWER4.

This also adds support for various built-in hardware found on Apple G5
hardware (e.g. the IBM CPC925 northbridge).

94b4a038a1 Adapt parts of the sparc64 Open Firmware bus enumeration code (in particular,
the code for parsing interrupt maps) to PowerPC and reflect their new MI
status by moving them to the shared dev/ofw directory.

This commit also modifies the OFW PCI enumeration procedure on PowerPC to
allow the bus to find non-firmware-enumerated devices that Apple likes to add,
and adds some useful Open Firmware properties (compat and name) to the pnpinfo
string of children on OFW SBus, EBus, PCI, and MacIO links. Because of the
change to PCI enumeration on PowerPC, X has started working again on PPC
machines with Grackle hostbridges.

68124cc7f8 Allow OFW syscons to restore itself when the X server exits or there is a VT switch
by redoing the Open Firmware card initialization calls in ofwfb_set_mode(). This
uses the same trick (setting V_ADP_MODECHANGE) to arrange this as machfb(4) and
creatorfb(4).

51d163d3e9 Convert PowerPC AIM PCI and nexus busses to standard OFW bus interface. This
simplifies certain device attachments (Kauai ATA, for instance), and makes
possible others on new hardware.

On G5 systems, there are several otherwise standard PCI devices
(Serverworks SATA) that will not allow their interrupt properties to be
written, so this information must be supplied directly from Open Firmware.

d3e5e8d1b6 Improve rev 183168, so that if /chosen/stdout is connected to the serial
port by OF the syscons won't take over console. Only attach syscons to "screen"
if /chosen/stdout is not connected, which could be the case when loader(8)
is booted directly from the OF. This fixes Marcel's Xserver.

ccb33393cc When attaching framebuffer to "/chosen/stdout" node fails, try attaching
to "screen" node directly. The problem is that by default OF on some (all?)
Macs either doesn't provide "/chosen/stdout" or redirects it somewhere,
unless you boot in manual mode via CMD-ALT-O-F. It's nice to see normal
FreeBSD boot output instead of blank gray screen.

04dda605c5 - Make pcib_devclass private to sys/dev/pci/pci_pci.c and change all the
various pcib drivers to use their own private devclass_t variables for
  their modules.
- Use the DEFINE_CLASS_0() macro to declare drivers for the various pcib
  drivers while I'm here.

b7c96c0d0b Add a font width argument to vi_load_font_t, vi_save_font_t and vi_putm_t
and do some preparations for handling 12x22 fonts (currently lots of code
implies and/or hardcodes a font width of 8 pixels). This will be required
on sparc64 which uses a default font size of 12x22 in order to add font
loading and saving support as well as to use a syscons(4)-supplied mouse
pointer image.
This API breakage is committed now so it can be MFC'ed in time for 6.0
and later on upcoming framebuffer drivers destined for use on sparc64
and which are expected to rely on using font loading internally and on
a syscons(4)-supplied mouse pointer image can be easily MFC'ed to
RELENG_6 rather than requiring a backport.

b4ac36978f Mods for Xorg server:
- store assigned PCI addresses at cninit time for later mmap range
   check
 - implement set_border to scrub X remnants when switching back to VTYs
 - implement mmap, only allowing addresses within the range of the
   console adapter.
