In order to build the multiboot option rom, we need a Makefile and a tool
to sign the rom with.
Both are provided by this patch and mostly taken from the extboot source,
written by Anthony Liguori.
Once built, the resulting binary gets copied to pc-bios automatically.
Building also occurs automatically when on an x86 host.

This patch implements support for Multiboot on x86 for -kernel.
Multiboot is a "new" approach to get rid of different bootloaders, providing
a unified interface for the kernel. It supports command line options and
kernel modules.
The two probably best known projects using multiboot are Xen and GNU Hurd.
This implementation should be mostly feature-complete. It is missing VBE
extensions, but as no system uses them currently it does not really hurt.
To use multiboot, specify the kernel as -kernel option. Modules should be given
as -initrd options, seperated by a comma (,). -append also works.
Please bear in mind that grub also does gzip decompression, which qemu does
not do yet. To run existing images, please ungzip them first.
The guest multiboot loader code is implemented as option rom using int 19.
Parts of the work are based on efforts by Rene Rebe, who originally ported
my code to int 19.

Create a new -smbios option (x86-only) to allow binary SMBIOS entries
to be passed through to the BIOS or modify the default values of
individual fields of type 0 and 1 entries on the command line.
Binary SMBIOS entries can be generated as follows:
dmidecode -t 1 -u | grep $'^\t\t[^"]' | xargs -n1 | \
perl -lne 'printf "%c", hex($_)' > smbios_type_1.bin
These can then be passed to the BIOS using this switch:
-smbios file=smbios_type_1.bin
Command line generation supports the following syntax:
-smbios type=0[,vendor=str][,version=str][,date=str][,release=%d.%d]
-smbios type=1[,manufacturer=str][,product=str][,version=str][,serial=str]
[,uuid=$(uuidgen)][,sku=str][,family=str]
For instance, to add a serial number to the type 1 table:
-smbios type=1,serial=0123456789
Interface is extensible to support more fields/tables as needed.

The VNC protocol contains quite some constants, some of which are
currently hardcoded in the vnc.c code. This is not exactly pretty.
Let's move all those constants out to vnc.h, so they are clearly
separated. While at it, I also included other defines that will be
used later in this patch series.

Apparently, guests are very tolerant of corrupt ACPI tables because our
tables have been badly corrupted for some time now. A version of
Knoppix using a 2.6.11 kernel refused to boot and it turned out it was
due to the interrupt override table introduced by the recent HPET
commit.
This patch updates the BIOS and introduces a patch to pack the ACPI
tables. If you have a guest that used to work and is broken by the this
commit, let me know. We have some weird hacks in the tables that I
suspect are work arounds for this bug.

This patch adds HPET emulation. It can be disabled with -disable-hpet. An hpet
provides a more finely granular clocksource than otherwise available on PC.
This means that latency-dependent applications (e.g. multimedia) will generally
be smoother when using the HPET.

Since most IO devices are integrated into the 440EP chip, "Bamboo support"
mostly entails implementing the -kernel, -initrd, and -append options.
These options are implemented by loading the guest as if u-boot had done it,
i.e. loading a flat device tree, updating it to hold initrd addresses, ram
size, and command line, and passing the FDT address in r3.
Since we use it with KVM, we enable the virtio block driver and include hooks
necessary for KVM support.
