Alexey Kardashevskiy 92d7a30cb3 pseries: Update SLOF firmware image to qemu-slof-20150813
The changes are:
1. GPT support;
2. Much faster VGA support.

The full changelog is:
  > Add missing half word access case to _FASTRMOVE and _FASTMOVE
  > Remove unused RMOVE64 stub
  > fbuffer: Implement RFILL as an accelerated primitive
  > fbuffer: Implement MRMOVE as an accelerated primitive
  > fbuffer: Precalculate line length in bytes
  > terminal: Disable the terminal-write trace by default
  > boot: remove trailing ":" in the bootpath
  > ci: implement boot client interface
  > boot: bootpath should be complete device path
  > fbuffer: Use a smaller cursor
  > fbuffer: Improve invert-region helper
  > usb-hid: Caps is not always shift
  > cas: Increase FDT buffer size to accomodate larger ibm, cas node properties
  > README: Update with patch submittion note
  > disk-label: add support for booting from GPT FAT partition
  > disk-label: introduce helper to check fat filesystem
  > introduce 8-byte LE helpers
  > disk-label: simplify gpt-prep-partition? routine
  > fbuffer: introduce the invert-region-x helper
  > fbuffer: introduce the invert-region helper
  > fbuffer: simplify address computations in fb8-toggle-cursor

- 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
