   7 title: Linksys Northstar partitioning
   8
   9 description: |
  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.
