| 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 |

| 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. |
