0007 title: Linksys Northstar partitioning
0008
0009 description: |
0010 Linksys devices based on Broadcom Northstar architecture often use two
0011 firmware partitions. One is used for regular booting, the other is treated as
0012 fallback.
0013
0014 This binding allows defining all fixed partitions and marking those containing
0015 firmware. System can use that information e.g. for booting or flashing
0016 purposes.
