I removed this patch from my queue again. The ppc64-softmmu target can
execute -M PReP which in turn uses the fdc.

Out of curiosity - do you have actual 64bit guests being able to run on
PReP? :) Current Linux ditched its support...

Paul suggested that there has never ever been a 64bit PReP CPU so there is
no point in emulating it in QEMU. Or there is some reason for that?

IIUC, qemu-system-ppc64 (roughly speaking) emulates a superset of what
qemu-system-ppc does, not a different set of hardware.

Well, default-configs/ppc-softmmu.mak does not include default-configs/ppc64-softmmu.mak or vice versa so I would say these are pretty independent and I would simply remove CONFIG_PREP* from default-configs/ppc64-softmmu.mak.
