Overview

This device may be identical to the Netgear DGND3700v1.

It shares the same basic Foxconn board ID: U12L144T01

• Netgear DGND3700/DGND3800B on the OpenWrt wiki (board image)

Per the dmesg output, this device has a 128MB NAND Flash.

This appears to be in addition to the 32MB Flash listed

in the entry, just like the Netgear DGND3700v1.

brcm63xx: Add DGND3700 v1 / DGND3800B support This adds support for the Netgear DGND3700 v1 and DGND3800B. DGND3700 v1 and DGND3800B are exactly the same router, only one difference, the factory firmware. This patch produces two factory firmwares for each router. The router includes an onboard NAND flash for extra storage. NAND is currently not supported in bcm63xx, so no code added for this part. The NOR flash (32MB) is enough for storing an openwrt firmware. Signed-off-by: Daniel Gonzalez [jogo: Add back commit message from v1] Signed-off-by: Jonas Gorski
