[PATCH 0/2] Mac Old World ROM experiment

[BALATON Zoltan <balaton@eik.bme.hu>]

Based on https://github.com/dingusdev/dingusppc this series allows
experimenting with binary ROM image from a G3 beige machine. It does
not get very far though. Running with

-bios 78F57389.rom -d unimp,guest_errors -trace enable="pci*" | uniq -c

I get the logs below and hangs reading the last reg. It seems to
expect macio to be mapped at 0xf3000000 (also confirmed by comments in
https://github.com/dingusdev/dingusppc/blob/master/devices/macio.h and
some logs I've found on-line) but I don't see where it would set this
up so maybe this needs to be mapped by default there?

Regards,
BALATON Zoltan
