The Status register in the PCI config space has some read-only bits.
Any writes to those bits should be masked out.

Since pci.c creates network devices, anything that links against pci.c
(everything) has to link against all network devices. Since virtio-net
also requires virtio, we might as well link every target against all of
the virtio devices.
This suggests that the pci.c network device creation function needs some
refactoring.

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.

Wire up the system-on-chip devices present on 440EP chips.
This patch is a little unusual in that qemu doesn't actually emulate the 440
core, but we use this board code with KVM (which does). If/when 440 core
emulation is supported, the kvm_enabled() hack can be removed.

Also add code that will copy the host's CPU and timebase frequencies to the

To implement the -kernel, -initrd, and -append options, 4xx board emulation
must load the guest kernel as if firmware had loaded it. Where u-boot would be
the firmware, we must load the flat device tree into memory and set key fields
such as /chosen/bootargs.
This patch introduces a dependency on libfdt for flat device tree support.

The 4xx SDRAM controller supports a small number of banks, and each bank must
be one of a small set of sizes. The number of banks and the supported sizes
varies by SoC.
This function uses the user-specified RAM size to fill in the "ram_bases" and
"ram_sizes" arrays required by ppc4xx_sdram_init().
