Subject: ramips: add support for ZBT WE3526
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9996480b0ee80456af0b9fc3d44580393b09c84b;p=openwrt%2Fstaging%2Flinusw.git

ramips: add support for ZBT WE3526

This is a variant of the ZBT WG3526 with a few minor modifications.
The wifi chips are swapped, and there is no GPIO controllable status
LED. There is also no SATA port.

Specifications:

- MT7621AT (880 MHz)
- 512 MB RAM
- 16 MB Flash (SPI NOR)
- 5x 1Gbps Ethernet (built-in switch)
- MT7612E 802.11ac 5 GHz WLAN
- MT7603E 802.11n 2.4 GHz WLAN
