From: Fabio Estevam Date: Mon, 1 Aug 2016 15:27:11 +0000 (-0300) Subject: configs: imx6ulpico: Add Wifi support X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=02bb84cb600fbaa81a1a951206dfb6e167afc6f3;p=buildroot.git configs: imx6ulpico: Add Wifi support imx6ulpico has a BCM4339 Wifi chip. Add Wifi support by default to allow a better customer experience. The dts patch has already been sent to the linux-arm-kernel list and we can remove it once it reaches a mainline kernel (in version 4.9 probably).
