I moved this comment to the top of the file, since it serves as more of
a documentation bit for the controller itself, and is not specific to the
function it was attached to, strictly speaking.

That said, I wonder if we should include this at all?  The file name might
and most likely will eventually change, as the datasheet gets updated to
include new revisions and erratas, etc.

So, I wonder if this is simply better to be included in the datasheet
itself, or some product guide and such, where Renesas can keep this up to
date and the users appraised of what they need to do to convert the
firmware correctly.

Users who do not have the datasheet and are not licensed wouldn't care.
