From 3bc6968adc7b1926f4582a33a33ad42d9b302ce0 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Sun, 29 Aug 2010 17:08:41 +0200 Subject: [PATCH] MIPS: AR7: Initialize GPIO earlier In order to detect the Titan variant, we must initialize GPIOs earlier since detection relies on some GPIO values to be set.
