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. I've set this partition to read-only for now
The following patch works around both of these issues.
