After reading some other messages about this I realize it's not very
much you can do with the standard frameworks and you definately
need something like this. Not like I have any better idea.

Arnd and Greg are misc maintainers so not you will need to
talk to them.

I would opt to put it in drivers/soc/aspeed though.
