Hi Magnus,

Thank you for the patches.

Do you mean s/####sfx/##sfx/ ?

I would have preferred keeping the trailing semicolon (and comma in the 
RZ_GROUPS macro) out of the macro, but that won't be possible as the 
RZ_PIN_AND_MUX and RZ_GROUPS macros are used as arguments to the SCIF macros 
in the next patch.

Can't you replace __RZ_GROUPS() by __stringify() ?

I think this should be part of patch 04/05.
