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