target-mips: DMA support for RC4030 chipset
Attached patch implements DMA support to RC4030 chipset and simplifies

Config register has not a clear meaning (only one value is always valid,
and sometimes another one), so use a magic value instead.

Parse --cc and --cross-prefix earlier and use CC to determine cpu and host
We have been relying on uname to determine the host cpu architecture and
operating system. This is totally broken for cross compilation. It was
workable in the past because you can manually override both settings but after
the host USB passthrough refactoring, cross host builds were broken.
This moves the parsing of --cc and --cross-prefix to before the probes for cpu
and host. Complation testing is used to determine the host and CPU types. I've
only added checks for i386, x86_64, Linux, and Windows since these are the only
platforms I have access to for testing. Everything else falls back to uname.
It should be relatively easy to add the right checks for other platforms and
eliminate uname altogether.

Make sure ACPI structures are byte-aligned
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.

When -icount is used and a TB is recompiled due to an IO access
shortly after an IRQ has been raised, env->exception_index will still be set
to EXCP_IRQ when cpu_io_recompile calls cpu_resume_from_signal.
This causes qemu to repeat the IRQ trap, with disasterous consequences.
I suspect this "works" most of the time because linux tends to drop back to
svc mode before doing actual IRQ processing, and be fairly
tolerant of spurious IRQ traps.

target-ppc: IBM PowerPC 440EP Bamboo reference board emulation
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.
