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.
