This command is currently monolithic and does not support scripts which want to adjust the boot process. This series updates it to be more like 'bootm', in that it has sub-commands for each stage of the boot. This allows some stages to be adjusted or skipped.
It also adds a way to dump out the setup block.
With these changes it is possible to boot an x86 Chrome OS image from a script.
Changes in v2: - Fix comment about argv[0] in do_zboot_parent() - Add a comment explaining the logic for a specified setup-base address
