[Qemu-devel] [PATCH 00/12] S390: Add virtio-ccw firmware

[Alexander Graf]

We used to be able to boot from the virtio-s390 machine using a
modified version of zipl. However, for our new virtio-ccw machine,
there was not such support available.

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.
