7title: Linksys Northstar partitioning
8
9description: |
10  Linksys devices based on Broadcom Northstar architecture often use two
11  firmware partitions. One is used for regular booting, the other is treated as
12  fallback.
13
14  This binding allows defining all fixed partitions and marking those containing
15  firmware. System can use that information e.g. for booting or flashing
16  purposes.
