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.
