Hmmm... I have to admit that I'm biased he. My primary interest at
the moment is obviously just to get the MPC512x stuff into mainline,
and thus I'm not happy about extending the scope of the isse to other
processors.
>From the technical point of view you are right, but I have to admit
that I don't see which direction we should go from here. If we keep in
mind that the same FEC core is also used in various i.MX platforms (=
ARM processors), we probably cannot come up with a clean, unique
implementation that covers all uses.
That's why I asked Grant how to address this. I also added Kumar to
the Cc: list - mayby he has some ideas as well?
Best regards,
Wolfgang Denk

The day-to-day travails of the IBM programmer are so amusing to most
of us who are fortunate enough never to have been one - like watching
Charlie Chaplin trying to cook a shoe.
