   4 Subject: [PATCH] ARM: dts: BCM5301X: Correct description of TP-Link partitions
   5 MIME-Version: 1.0
   6 Content-Type: text/plain; charset=UTF-8
   7 Content-Transfer-Encoding: 8bit
   8
   9 TP-Link routers have flash space partitioned according to the partitions
  10 table. It may look like fixed partitioning but those partitions can be
  11 actually reorganized. New can be added (or some removed), offsets and
  12 sizes may change.
  13
  14 Fix DT to use binding for the TP-Link SafeLoader partitioning method.
