Alexey Kardashevskiy d21bbcc655 pseries: Update SLOF firmware image to qemu-slof-20180621
The changes are:
1. fixed broken_sc1;
2. added switching between boot consoles;
3. added PXE boot.

The full list is:
 > lib/libnet/pxelinux: Fix two off-by-one bugs in the pxelinux.cfg parser
 > lib/libnet/pxelinux: Make the size handling for pxelinux_load_cfg more logical
 > libc: Add a simple implementation of an assert() function
 > libnet: Support UUID-based pxelinux.cfg file names
 > slof: Add a helper function to get the contents of a property in C code
 > libnet: Add support for DHCPv4 options 209 and 210
 > libnet: Wire up pxelinux.cfg network booting
 > libnet: Add functions for downloading and parsing pxelinux.cfg files
 > libnet: Put code for determing TFTP error strings into a separate function
 > libc: Add the snprintf() function
 > libnet: Pass ip_version via struct filename_ip
 > resolve ihandle and xt handle in the input command (like for the output)
 > Fix output word
 > obp-tftp: Make sure to not overwrite paflof in memory
 > libnet: Get rid of unused huge_load and block_size parameters
 > libc: Check for NULL pointers in free()
 > libc: Implement strrchr()
 > libnet: Get rid of unnecessary (char *) casts
 > broken_sc1: check for H_PRIVILEGE
 > OF: Use new property "stdout-path" for boot console

- 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-20180621.
- 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

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.
