[PATCH v3 0/8] s390x: Add support for virtio-scsi-pci boot device

[jrossi@linux.ibm.com]

From: Jared Rossi <jrossi@linux.ibm.com>

Add support for booting from SCSI devices with a virtio-scsi-pci controller.

Some minor clean-up is done with naming in order to clarify if the function
or value used with CCW, PCI, or generic IPL and to check if a PCI function
is already enabled.

Changes v2 -> v3:
    - Rebase on recently added Secure IPL features added to BIOS
    - Define PCI IPLB length using offset and sizeof rather than magic
    - Check for virtio setup failures during scsi setup
    - Fix commit messages
    - Update the title of patch 3 to indicate multiple lengths change

Jared Rossi (8):
  pc-bios/s390-ccw: Check if a PCI function is already enabled before
    trying to enable it
  hw/s390x/ipl: Fix incorrect PCI IPL block lengths
  pc-bios/s390-ccw: Use bus specific IPL_TYPE directly for scsi IPL
  s390x/ipl: Add PCI and bus fields to IplBlockQemuScsi
  pc-bios/s390-ccw: Abstract virtio_run() for generic use
  pc-bios/s390-ccw: Add support for virtio-scsi-pci IPL
  s390x: Find scsi-pci boot device and build IPLB
  tests/qtest: Add s390x PCI SCSI fallback test to cdrom-test.c
