Hi Roger
Same comment i just sent to Thomas:
The partition table should be a subnode of the mtd node and should be named
'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.
