Hi,
here is a patch that should add support for pata_macio driver in ofpath on oldworld.
I have bug #695945 on qemu too and it seems that pata_macio driver is used and
by default qemu-system-ppc emulates an oldworld AAPL,PowerMac G3.
quik-installer uses ofpath and it fails to translate the linux device path to
OpenFirmware path, because this combination pata_macio/oldworld/PowerMac G3 is
not dealt with.
As it said in the bug above, not sure "nvsetenv boot-device \"${ofpath}0\" in
quik-installer post-install is needed. I tested quik-installer without those
lines and the installer worked. But this was on qemu and I don't have real
hardware to check more.
So I added support to the ofpath script.
ofpath wouldn't fail and will provide an OF path and I could finish the
installation properly. I checked the generated path was ok from the OF prompt
of the qemu machine.
Let me know what you think of this.
Thanks!
