Hi Roland,

One more thing I noticed this time:

This should eventually both become run-time options based on the device tree.
I don't know if you planned to do that anyway, but if you want the same kernel
binary to be used for systems in different configurations, you cannot have
compile-time decisions that are exclusive-or. Since you don't support device
tree yet but plan to do that in the future, you could add a comment here
about it, or you could even prepare it for that case already by passing the
device into the functions that will be required for reading the properties.
