This patch adds ath79 support for Netgear WNDR3700v4.
Router was previously supported by ar71xx target only.
Note: device requires 'ar934x-nand' driver in kernel.
Specification
=============
* Description: Netgear WNDR3700v4
* Loader: U-boot
* SOC: Atheros AR9344 (560 MHz)
* RAM: 128 MiB
* Flash: 128 MiB (NAND)
- U-boot binary: 256 KiB
- U-boot environment: 256 KiB
- ART: 256 KiB
- POT: 512 KiB
- Language: 2 MiB
- Config: 512 KiB
- Traffic Meter: 3 MiB
- Firmware: 25 MiB
- ART Backup: 256 KiB
- Reserved: 96 MiB
* Ethernet: 5 x 10/100/1000 (4 x LAN, 1 x WAN) (AR8327)
* Wireless:
- 2.4 GHz b/g/n (internal)
- 5 GHz a/n (AR9580)
* USB: yes, 1 x USB 2.0
* Buttons:
- Reset
- WiFi (rfkill)
- WPS
* LEDs:
- Power (amber/green)
- WAN (amber/green)
- WLAN 2G (green)
- WLAN 5G (blue)
- 4 x LAN (amber/green)
- USB (green)
- WPS (amber/green)
* UART: 4-pin connector JP1, 3.3V (Vcc, TX, RX, GND), 115200 8N1
* Power supply: DC 12V 2.5A
* MAC addresses: LAN=WLAN2G on case label, WAN +1, WLAN5G +2
Installation
============
* TFTP recovery
* TFTP via U-boot prompt
* sysupgrade
* Web interface
Note about partitioning: firmware partition offset (0x6c0000) is
hardcoded into vendor's u-boot, so this partition cannot be moved
and resized to include Netgear-specific flash areas (pot, language,
config, traffic_meter) not used by OpenWrt.
