Oh, then it looks like *I* did not understand your mail correctly. It is 
absolutely necessary indeed that your architecture declares a 
GENERIC_GPIO config option. What I was trying to prevent you from doing 
was to put new "select GENERIC_GPIO" or "depends on GENERIC_GPIO" in 
your Kconfig files.

If the only reference to GENERIC_GPIO in your architecture or drivers is 
the declaration of this config option, then it is perfectly fine - I 
will take care of removing it when the time is right.

So I guess you guys are just fine - sorry about the misunderstanding!

Thanks,
Alex.
