Dong Jia Shi 9c9f5f311a pc-bios/s390-ccw: enable subchannel for IPL I/O devices
IPL should cause the IPL I/O device to become enabled. So when handling
the IPL program, we should set the E (Enable) bit. However, virtio-ccw
does not know whether it's dealing with an IPL device or not. Since
trying to perform I/O on a disabled device doesn't make any sense,
let's just always enable it. At the same time we can remove the
SCSW_FCTL_START_FUNC flag as it is ignored for msch anyway and did
not enable the device as intended.

- SeaBIOS (bios.bin) is the successor of pc bios.
  See http://www.seabios.org/ for more information.

- The VGA BIOS and the Cirrus VGA BIOS come from the LGPL VGA bios
  project (http://www.nongnu.org/vgabios/).

- The PowerPC Open Hack'Ware Open Firmware Compatible BIOS is
  available at http://repo.or.cz/w/openhackware.git.

- 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),
  Sparc32 (including QEMU,tcx.bin and QEMU,cgthree.bin) and Sparc64 are built
  from OpenBIOS SVN revision 1280.

- SLOF (Slimline Open Firmware) is a free IEEE 1275 Open Firmware
  implementation for certain IBM POWER hardware.  The sources are at
  https://github.com/aik/SLOF, and the image currently in qemu is
  built from git tag qemu-slof-20160223.

- 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-project.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:

- The sources for the Alpha palcode image is available from:
  git://github.com/rth7680/qemu-palcode.git

- The u-boot binary for e500 comes from the upstream denx u-boot project where
  it was compiled using the qemu-ppce500 target.
  A git mirror is available at: git://git.qemu-project.org/u-boot.git
  The hash used to compile the current version is: 2072e72
