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: Linksys Northstar partitioning
|
|
|
|
description: |
|
|
Linksys devices based on Broadcom Northstar architecture often use 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.
