+    MIPS: BCM47XX: Get GPIO pin from nvram configuration
+    
+    The nvram contains some gpio configuration for boards. It is stored in
+    a gpio<number>=name format e.g.
+    gpio8=wps_button
+    gpio4=robo_reset
+    
+    This patches adds a function to parse these entries, so other driver
+    can use it.
