Parser compatibles cannot be used anywhere, and the list is limited. In order to constrain this list, enumerate them all under the top "partitions" subnode. New parsers will have to add their own compatible here as well.

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.
