[Qemu-devel] [PATCH v5 12/12] s390-ccw: interactive boot menu for scsi

["Collin L. Walling" <walling@linux.vnet.ibm.com>]

Interactive boot menu for scsi. This follows a similar procedure
as the interactive menu for eckd dasd. An example follows:

    s390x Enumerated Boot Menu.

    3 entries detected. Select from index 0 to 2.
