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.
