Collin L. Walling 26b2a2a491 s390-ccw: parse and set boot menu options
Set boot menu options for an s390 guest and store them in
the iplb. These options are set via the QEMU command line
option:

    -boot menu=on|off[,splash-time=X]

or via the libvirt domain xml:

    <os>
      <bootmenu enable='yes|no' timeout='X'/>
    </os>

Where X represents some positive integer representing
milliseconds.

Any value set for loadparm will override all boot menu options.
If loadparm=PROMPT, then the menu will be enabled without a
timeout.

- OpenBIOS (http://www.openbios.org/) is a free (GPL v2) portable
  firmware implementation. The goal is to implement a 100% IEEE
  1275-1994 (referred to as Open Firmware) compliant firmware.
  The included images for PowerPC (for 32 and 64 bit PPC CPUs),

  built from git tag qemu-slof-20171214.

- sgabios (the Serial Graphics Adapter option ROM) provides a means for
  legacy x86 software to communicate with an attached serial console as
  if a video card were attached.  The master sources reside in a subversion
  repository at http://sgabios.googlecode.com/svn/trunk.  A git mirror is
  available at git://git.qemu.org/sgabios.git.

- The PXE roms come from the iPXE project. Built with BANNER_TIME 0.
  Sources available at http://ipxe.org.  Vendor:Device ID -> ROM mapping:
