+Subject: [PATCH] dt-bindings: mtd: move partition binding to its own file
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Single partition binding is quite common and may be:
+1. Used by multiple parsers
+2. Extended for more specific cases
+
+Move it to separated file to avoid code duplication.

+Content-Type: text/plain; charset=UTF-8

+
+BCM4908 uses fixed partitions layout but function of some partitions may
+vary. Some devices use multiple firmware partitions and those partitions
+should be marked to let system discover their purpose.

++description: |
++ Broadcom BCM4908 CFE bootloader supports two firmware partitions. One is used
++ for regular booting, the other is treated as fallback.
++
++ This binding allows defining all fixed partitions and marking those containing
++ firmware. System can use that information e.g. for booting or flashing
++ purposes.
