Christian Borntraeger af3c15fee5 pc-bios/s390-ccw: avoid floating point operations
Some gcc versions (e.g. Fedora 22 gcc 5.1.1) seem to use floating
point registers for spilling and filling of general purpose registers.
As the BIOS does not activate the AFP register setting of CR0 this can
cause data exception program checks.
Disallow floating point in the BIOS as a simple solution.

- 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-20150813.

- 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:

	8086:100e -> pxe-e1000.rom
	8086:1209 -> pxe-eepro100.rom
	1050:0940 -> pxe-ne2k_pci.rom
	1022:2000 -> pxe-pcnet.rom
	10ec:8139 -> pxe-rtl8139.rom
	1af4:1000 -> pxe-virtio.rom

- The S390 zipl loader is an addition to the official IBM s390-tools
  package. That fork is maintained in its own git repository at:
  git://repo.or.cz/s390-tools.git

- 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
