+Subject: [PATCH] ARM: dts: BCM5301X: Correct description of TP-Link partitions
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+TP-Link routers have flash space partitioned according to the partitions
+table. It may look like fixed partitioning but those partitions can be
+actually reorganized. New can be added (or some removed), offsets and
+sizes may change.
+
+Fix DT to use binding for the TP-Link SafeLoader partitioning method.
