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