[OpenWrt-Devel] [PATCH 2/2] brcm47xx: Add initial support for Linksys WUMC710

Michał Osowiecki Mon, 01 Feb 2016 11:02:15 -0800

Linksys WUMC710 (and probably TrendNET TEW-812DRU) needs specificfirmware images.This patch adds (previously posted on list) trx2uimage tool and modifiesMakefile for WUMC710
