+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.

+                values are the same, but may differ if device has bad
+                eraseblocks on a flash.
