This patch set adds a tiny but of firmware to the game, so that we
get the same functionality back that we used to have on virtio-s390.
It should live in the QEMU tree, so that we can easily extend it
to support more fancy features, like asking the user to choose which
entry to boot, or boot menus.

Thanks.
In general this seems to work for scsi disks or image files that contain
a scsi bootmap. There are several things that we should fix or extend, though:
- disabled wait
- make cio better
- pass a device id
- loadparm
- dasd bootmap (which is not architectured, but pretty similar to the scsi one)
Can you provide a qemu tree so that we can help to fix/extend this?
I think this should go into 1.5, lets see how much we can improve this before
