(Russell, a question for you at the bottom)

Russell, the patch Alex sent to move firmware_ops into drivers/firmware
was rejected, so I don't think we can update this series to move the
code there instead.

So, are you OK with merging this series as-is, in arch/arm/firmware? If
you could ack the patch/series to indicate that, it would be awesome.
Thanks.
