When using the escc with Linux, we need interrupts. So instead of

a dummy device, let's just map them to the openpic we have anyways.
This makes Linux on PPC64 with console=ttyPZ0 work.
With these patches and OpenBIOS r646, booting 'install64' on the
following Debian CDs worked for me:
debian-40r4a-powerpc-netinst.iso
debian-503-powerpc-netinst.iso
By default however you get the following error:
invalid/unsupported opcode: 1e - 12 - 1b (782106e4) 00000000014080e4 1
invalid/unsupported opcode: 00 - 00 - 00 (00000000) 0000000000008734 0
which translates to: qemu-system-ppc64 is using a 32-bit CPU by default.
'-cpu ppc64' (970FX according to OpenBIOS) worked, while '-cpu 970'
was not recognized by OpenBIOS.
If you change only the CPU to 'ppc64', it will be rejected:
qemu: hardware error: Bus model not supported on OldWorld Mac machine
That's why Alex mentioned '-M mac99' elsewhere, I guess. Can't we
change the defaults? I believe the G5 was the first 64-bit Mac and is
considered New World, so Old World shouldn't even be selectable IMO.
`install64 console=ttyPZ0` only gets me to the penguin and appears to
hang...
`install64` gets me through to the installer screen on Linux/amd64
host. There are merely some FATALs visible while trying to load
drivers for therm_* and windfarm_* devices ("No such device").

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