From d04056e5ea64debd69b075f2fc9ed6a44a2f57a2 Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Thu, 11 Jan 2018 00:22:42 +0100 Subject: ar71xx: disable devicetree support While we'd like to convert ar71xx to DT-based configuration eventually, we aren't quite there yet, and shipping half-baked DT support that is not used at all wastes precious space. Saves ~120KB before LZMA, ~33KB after LZMA. Run-tested on TP-Link CPE510 and TL-WR841 v7.
