[OpenWrt-Devel] [PATCH v3] ramips: Add support for Netgear EX2700

Thu Jan 21 17:23:49 EST 2016

This patch adds support for the Netgear EX2700 and builds an approriate
sysupgrade image.

What's missing is the option to build a factory image flashable via the
router's stock web interface, but this approach is hindered by the fact
that u-boot operforms an additional integrity check, which expects a
uImage header in the last 64 bytes of the "kernel" partition, which
the bootloader expects to be 960k, a size exceeded by the standard
OpenWrt kernel.

Changes for v3:
* Fix led name in /etc/board.d/01_leds
* Cleanup device tree

Changes for v2:
* Fix alphabetical ordering (image/Makefile is not really sorted, so I've
put the EX2700 immediately below the E1700).
