Is this intentional?

Why is it needed? Was the old address wrong? Does it change anything
functionally?

If it is needed it seems like a separate change - unless there's some
reason it's tied to adding this driver?

Should this really apply only to the lantiq,vr9 case or also to the
similar lantiq,grx390 & lantiq,ar10 paths?

Whatever the answers to these questions it would be good to include them
in the commit message.

Thanks,
    Paul
