Hi !

Well, that isn't really the question :-) Is there any interest in
ensuring that your current Sky is supported by upstream linux kernels or
not ? As I said, the current kernel seems to contain code relative to
the Sky CPU that is never enabled and potentially has issue. Are you
guys interested in fixing this so that upstream linux supports your
existing products, or should we just rip the code out ?

Cheers,
Ben.
