Add boot script (boot.scr) support. If no boot script are found, it boots as usual.
Instead of extending the specialized boot script, it would belovely to see the odroid board switch to distro boot commands for a more standardized boot sequence.
This would be a better solution but also a much bigger work. Morevover, the backward compatibility will be harder to verify. So, for now, I will stick with this patch. But if you want to do it, please do it. :)

For reference, if you need an example how to add that while staying backwards compatible see my patchset for am335x boards which did something like that:
