Rafał Miłecki 6e9dff6fe3 dt-bindings: mtd: add binding for BCM4908 partitions
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.

title: Broadcom BCM4908 partitioning
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.
