From a393c46b493de18242105c7f7e713822d179a717 Mon Sep 17 00:00:00 2001 From: Jaya Kumar Date: Sun, 20 Apr 2008 07:25:00 +0100 Subject: [ARM] 5006/1: Gumstix GPIO header fixup and defconfig fixup This patch adds the include of the GPIO header needed to make gumstix build. The defconfig is updated to 2.6.25 and disables PCMCIA since that has not yet been implemented for gumstix.
