+   m) Chipselect/Local Bus
+
+   Properties:
+   - name : Should be localbus
+   - #address-cells : Should be either two or three.  The first cell is the
+                      chipselect number, and the remaining cells are the
+                      offset into the chipselect.
+   - #size-cells : Either one or two, depending on how large each chipselect
+                   can be.
+   - ranges : Each range corresponds to a single chipselect, and cover
+              the entire access window as configured.
+
+   Example:
+        localbus@f0010100 {
