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