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.
