Alexey Kardashevskiy c334e5f382 pseries: Update SLOF firmware image to qemu-slof-20171214
The main changes are:
- able to handle more devices with specified bootindex;
- implements flatten device tree rendering, for both QEMU and guest kernel.

The full list is:
  > boot: use a temporary bootdev-buf
  > boot: do not concatenate bootdev
  > libvirtio: Mark struct virtio_scsi_req_cmd as packed
  > fdt: Implement "fdt-fetch" method for client interface
  > rtas: Store RTAS address and entry in the device tree
  > board-qemu: Fix slof-build-id length
  > fdt: Pass the resulting device tree to QEMU
  > fdt: Fix version and add a word for FDT header size
  > tree: Rework set-chosen-cpu and store /chosen ihandle and phandle
  > node: Add some documentation
  > Revert various SLOF-to-QEMU private hypercalls
  > Use input-device and output-device
  > netboot: Create bootp-response when bootp is used
  > libnet/ipv6: assign times_asked value directly
  > usb-xhci: Reset ERSTSZ together with ERSTBA
  > virtio-net: rework the driver to support multiple open
  > board-qemu: add private hcall to inform host on "phandle" update

- 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-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:
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 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.org/u-boot.git
The hash used to compile the current version is: 2072e72
- Skiboot (https://github.com/open-power/skiboot/) is an OPAL
(OpenPower Abstraction Layer) firmware for OpenPOWER systems. It can
run an hypervisor OS or simply a host OS on the "baremetal"
platform, also known as the PowerNV (Non-Virtualized) platform.
- QemuMacDrivers (https://github.com/ozbenh/QemuMacDrivers) is a project to
provide virtualised drivers for PPC MacOS guests.
