   4 Subject: [PATCH] firmware: bcm47xx_nvram: support small (0x6000 B) NVRAM
   5  partitions
   6
   7 Some old devices with 4 MiB flashes were using 0x1000 block size and
   8 could use smaller (0x6000 bytes) flash partition for storing NVRAM
   9 content. This adds support for reading NVRAM on Netgear WNR1000 V3.
