9description: |
10  This binding can be used on platforms which have strong conventions about
11  which portions of a flash are used for what purposes, but which don't use an
12  on-flash partition table such as RedBoot.
13
14  The partition table should be a node named "partitions". Partitions are then
15  defined as subnodes.
