[Qemu-devel] [PATCH] PPC: Use interrupts for escc

[Alexander Graf]

When using the escc with Linux, we need interrupts. So instead of creating
a dummy device, let's just map them to the openpic we have anyways.

This makes Linux on PPC64 with console=ttyPZ0 work.

Obviously, this change needs to be reflected in openbios. Patch for that
follows this one. Please update the binary then.
