+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.
