Let's give Amlogic some more time then. I think it's better to merge other parts of the platform first when we can reasonably assume that we don't have to change the binding any more. It would be a shame to merge this now and then make it obsolete by implementing PSCI but still having to carry around the original code for compatibility reasons. Arnd
