as RedBoot.



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.

'partitions'. This node should have the following property:

- 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.
