I won't be able to fix this in the next time. I'm currently in the state of
moving and can't set up my hardware to test the changes. And I'm not willing
to submit changes without testing. And with testing I really mean testing it
against a running Crust firmware which touches the hwspinlock unit.

If someone wants to change that, I'm happy to see it working out, but please
do it properly. Just testing the locks in Linux only is not sufficient. If
some directions are required, I still have my working repo up at Github:
https://github.com/wgottwalt/sunxi_hwspinlock
It may be a bit dated, but should be a good start.

Greetings,
Will
