Reposting fom qemu tree now.
So I just sent patches for pcbios and seabios to fix this. Once
applied, reset works fine. Further, we can also fix PCI incompliancy in
cirrus, disabling memory and i/o on reset.
To apply these patches:
- apply pcbios and seabios patches
- generate binaries and commit
- apply this patchset
Michael S. Tsirkin (4):
qemu: update pcbios to enable i/o for cirrus
qemu: update seabios to enable i/o for cirrus
qemu: make cirrus init value pci spec compliant
qemu: cleanup unused macros in cirrus
