The partition table should be a subnode of the mtd node and should be named
-'partitions'. Partitions are defined in subnodes of the partitions node.

+- compatible : (required) must be "fixed-partitions"
+Partitions are then defined in subnodes of the partitions node.
For backwards compatibility partitions as direct subnodes of the mtd device are
supported. This use is discouraged.
