Currently, the emulated pSeries machine requires the use of the
-kernel parameter in order to explicitly load a guest kernel. This
means booting from the virtual disk, cdrom or network is not possible.
This patch addresses this limitation by inserting a within-partition
firmware image (derived from the "SLOF" free Open Firmware project).
If -kernel is not specified, qemu will now load the SLOF image, which
has access to the qemu boot device list through the device tree, and
can boot from any of the usual virtual devices.
In order to support the new firmware, an extension to the emulated
machine/hypervisor is necessary. Unlike Linux, which expects
multi-CPU entry to be handled kexec() style, the SLOF firmware expects
only one CPU to be active at entry, and to use a hypervisor RTAS
method to enable the other CPUs one by one.
This patch also implements this 'start-cpu' method, so that SLOF can
start the secondary CPUs and marshal them into the kexec() holding
pattern ready for entry into the guest OS. Linux should, and in the
future might directly use the start-cpu method to enable initially
disabled CPUs, but for now it does require kexec() entry.

Patching the rom data during load (in qemu) now
also supports i82801 (which had no rom file).
We only need a single rom file for the whole device family,
so remove the second one which is no longer needed.

This patch adds a firmware blob to the S390 target. The blob is a simple
implementation of a virtio client that tries to read the second stage
bootloader from sectors described as of offset 0x20 in the MBR.
In combination with an updated zipl this allows for booting from virtio
block devices. This firmware is built from the same sources as the second
stage bootloader. You can find a virtio capable s390-tools in this repo:

Only two boot ROM files are needed for all devices.
* Add these GPXE ROM files using new naming convention
(as discussed on qemu-devel). Both files were created
with http://rom-o-matic.net/, PCI vendor / device ids
as in ROM filenames and option BANNER_TIMEOUT = 0.
* Remove old PXE ROM file for i82559er.
It was replaced by gpxe-eepro100-80861209.rom.
* Update pc-bios/README (and sort entries).
Full support still needs additional eepro100 fixes.
