When we talked about this earlier on the DT bindings list the consensus seemed to be that configuration MMIO ranges should only be used if the underlying memory was exactly ECAM, and was not to be used for random configuration related register blocks. The rational being that generic code, upon seeing that ranges entry, could just go ahead and assume ECAM mapping.
