Hi Thomas,
Per curiosity. I understand that a 64-bit ppc CPU is expected to support
32-bit ppc code, but does QEMU really need to emulate setups that likely
never existed in real life (like a PowerMac G5 or a pSeries with an
internal floppy disk controller for example) ?
I ask because Murilo and I had a chat about removing CONFIG_FDC from
default-configs/ppc64-softmmu.mak the other day :)
Cheers,
