   7 title: Broadcom BCM4908 partitioning

   9 description: |
  10   Broadcom BCM4908 CFE bootloader supports two firmware partitions. One is used
  11   for regular booting, the other is treated as fallback.
  12
  13   This binding allows defining all fixed partitions and marking those containing
  14   firmware. System can use that information e.g. for booting or flashing
  15   purposes.
