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.

+
|

+ This binding allows defining all fixed partitions and marking those containing

+ firmware. System can use that information e.g. for booting or flashing
