This is to support booting from vfio-ccw dasd devices. We basically implement
the real hardware ipl procedure. This allows for booting Linux guests on
vfio-ccw devices.

vfio-ccw's channel program prefetch algorithm complicates ipl because most ipl
channel programs dynamically modify themselves. Details on the ipl process and
how we worked around this issue can be found in docs/devel/s390-dasd-ipl.txt.

Changelog

Ping. Thomas or Christian, are you ready to pick this series up or do you feel we need any 
more work?

Sorry, I was out of office during the last week ... I'll try to have a
closer look during the next days... (but it's too late for 4.0 now since
we're already in the freeze period).

The regression with non-bootable devices still exists, i.e. this used to
work before:

 $ qemu-system-s390x -enable-kvm -nographic -device x-terminal3270 \
     -device virtio-blk-ccw,drive=dr1 \
     -drive if=none,id=dr1,format=qcow2,file=guest.qcow2

... but now aborts with:

 Attempting to boot from unexpected device type: 0x0000000000003270

Can you somehow limit the choice of devices here that are considered for
booting?
