   4 Subject: [PATCH] ARM: dts: BCM5301X: Linksys EA9500 add fixed partitions
   5
   6 This router has dual paritions to store trx firmware image and
   7 dual partitions for nvram. The second one in each of these cases acts
   8 as a backup store.
   9
  10 When tested with OpenWrt, the default partition parser causes two issues:
  11
  12 1. It labels both nvram partitions as nvram. In factory, second one is
  13 labeled devinfo.
  14 2. It parses second trx image and tries to create second 'linux' partition
  15 and fails with - cannot create duplicate 'linux' partition
  16
  17 The following patch works around both of these issues.
