+* Common properties of all MTD devices
+
+Optional properties:
+- label: user-defined MTD device name. Can be used to assign user
+  friendly names to MTD devices (instead of the flash model or flash
+  controller based name) in order to ease flash device identification
+  and/or describe what they are used for.
+
+Example:
+
+	flash at 0 {
+		label = "System-firmware";
+
+		/* flash type specific properties */
+	};
