This would avoid panicking with a > device tree that have different default values. Unfortunately the #address-cells nodes etc affect only the children of the current node. The sizes for this node are controlled by the parent's sizes. In practice #address-cells more than 2 (i.e. using 16 or more bytes) seem like they are going to be rather rare.
