No problem - we fix it !

I hoped to have a right get_cpu_rev() for VF610, too. Then I checked in
the VF610 manual, but I found revision only for specific controllers -
EHCI, etc. I have not found anything equivalent, but maybe it is better
hidden.

Of course, we can do with an empty function if we have not something
better. Maybe do you can check in Freescale if there is a way to get the
cpu revision instead of a dummy ?

Thanks,
Stefano Babic
