Remove the ofb driver. I'm not interested in trying to make this work.
It should be replaced with the genfb driver, which I have added,
commented out because that driver needs work before it will function on
ofppc. (it's too panic-happy, and ofppc needs a working autoconf.c)
Change the way we do isa_inb/outb. The new way is a slightly nastier
hack, but won't run afoul of the other isa drivers as much.
Fix ofw_consinit.c to remove the dependency on ofb.
Write a complete OF boot console into ofw_consinit.c and rewire a bunch
of the ifdef logic in that file to use it when appropriate on both macppc
and ofppc. Get rid of the attempt to wire up the serial console early,
as that is extremely difficult on ofppc. Yank all the console code out
of ofppc/machdep.c. (This is a boot console only, not a full blown
console like ofcons.c)
Delete all the ofbus references out of the config files, and pull in
dev/ofw/openfirmio.c and dev/ofw/ofw_subr.c directly rather than pulling
in files.ofw. It might be worth going back and adding a files.ofw-nobus
to that directory to allow pulling in the openfirmware driver without
pulling in the whole ofbus mess.
Change rtas driver to connect directly to mainbus, like the PCI bus nodes do.
on OFW, and passes them on to ofwoea_batmap correctly. With this fix,
ofppc now properly initializes all of it's batmappings.
Kept the macppc specific override of the bitmap, but surrounded it with
an #ifdef macppc. It would probably be worth testing macppc without this
ifdef to see if it works there as well.
working properly. This is still a work in progress, and all work so far
has been based on the PegasosII machne.
1) Rewrite how the ISA memory and IO space maps are found. More work
will still need to be done in this area.
2) Add a new OFW method of pci configuration. So far I can only get this
to work on the primary PCI bus on the Pegasos. Unsure if this is a
pegasos bug or a code bug.
3) Add the rtas device to ofppc, and add an "rtas_reboot" function to
rtas to allow me to reboot the PegasosII. The rtas driver works, and is
a great start but needs to be changed slightly to allow easier access to
the functions from outside the driver.
4) Fix a number of bugs that existed in the shared PCI code for ofw that
probably weren't tickled by macppc.
There is much much more left to do here, this is all still a work in
progress, but this commit will allow other people to play around with the
code if they want to.
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.

This allows us to convert aucom to just another com attachment, and cleanup

Additionally, we use a common com_cleanup routine rather than having a

This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.
