the call to pci_configure_bus(9) and it's supporting code is
copied verbatim from the prep port.
this allows us to completely remove the really gross pegasos
specific pegasospci_indirect_attach_hook() that set various
pci command regs, since all those devices (mostly work now,
see below) and additionally PCI plugin cards work now too.
it also makes the pegasos onboard vr(4) ethernet work with
disk boot (it previously only worked with netboot.)
in the generic macppc ofw pci conf hook and for pegasos,
don't configure the viaide(4) device, and don't configure
memory space on the fwohci(4) device.
with this, and my other recent ofppc/ppc changes the pegasos
port is mostly functional. the marvell gige is not working,
and my 512mb appears as only about 256mb, but otherwise
this port is almost done!
USB works fine. IEEE1394 is untested. Audio doesn't work (playing white noise).
Need to set IO/MEM-enable for IEEE1394 and audio, as the firmware (Smart
Firmware 1.2) doesn't do it.
Patch approved by Tim Rightnour.
better on ofppc. In doing so, we also move a few functions around in
macppc and the generic ofw powerpc stuff to allow better sharing of code.
Also, introduce a model_init function.
move ofb_cons.c from macppc/dev to powerpc/oea and rename it to rascons.
This gets rid of some naming confusion, and makes it OFW-MI rather than
macppc specific.
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.
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.
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.
