[Qemu-devel] [PATCH 06/10] PPC: Use macio IDE controller for Newworld

[Alexander Graf <agraf@suse.de>]

Per default Linux doesn't come with a lot of storage adapters enabled on
Mac configurations. The one that's pretty much always present is the pmac-ide,
while the cmd64x is almost never included in any distribution.

So let's switch to use the MacIO based IDE controller. There is corresponding
OpenBIOS code to get interrupts working properly.
