Benjamin Herrenschmidt 4d8d5467cd pseries: SLOF PCI flag day
Currently on the pseries machine the SLOF firmware is used normally,
but we bypass it when -kernel is specified.  Having these two

different boot paths can cause some confusion.

In particular at present we need to "probe" the (emulated) PCI bus and
produce device tree nodes for the PCI devices in qemu, for the -kernel
case.  In the SLOF case, it takes the device tree from qemu adds some
stuff to it then passes it on to the kernel.

It's been decided that a better approach is to always boot through
SLOF, even when using -kernel.  WIth this approach we can leave PCI
probing and device node creation to SLOF in all cases which removes a
bunch of code in qemu, and avoids iterating the PCI devices from the
machine specific init code which we're not supposed to do.

This patch changes qemu to always boot through SLOF, and not to create
PCI nodes.  Simultaneously it updates the included version of SLOF
(submodule and binary image) to one which supports (and requires) the
new approach.

The new SLOF version also includes a number of unrelated enhancements:
support for booting from virtio-pci devices and e1000, greatly
improved FCode support and many bugfixes.  It also makes SLOF ready to
be used even when specifying a kernel on the qemu command line.

- 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

  The included images for PowerPC (for 32 and 64 bit PPC CPUs),
  Sparc32 and Sparc64 are built from OpenBIOS SVN revision
  1047.

- SLOF (Slimline Open Firmware) is a free IEEE 1275 Open Firmware

  built from git tag qemu-slof-20120111.1.

- sgabios (the Serial Graphics Adapter option ROM) provides a means for
  legacy x86 software to communicate with an attached serial console as

  repository at http://sgabios.googlecode.com/svn/trunk.  A git mirror is
  available at git://git.qemu.org/sgabios.git.

  package. That fork is maintained in its own git repository at:
