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.

Subject: [PATCH] dt-bindings: mtd: add binding for BCM4908 partitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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.
