@@ -14,6 +14,13 @@ method is used for a given flash device. To describe the method there should be
a subnode of the flash device that is named 'partitions'. It must have a
'compatible' property, which is used to identify the method to use.
+When a single partition is represented with a DT node (it depends on a used
+format) it may also be described using above rules ('compatible' and optionally
+some extra properties / subnodes). It allows describing more complex,
+hierarchical (multi-level) layouts and should be used if there is some
+significant relation between partitions or some partition internally uses
+another partitioning method.

Available bindings are listed in the "partitions" subdirectory.
