This patch adds support for DRAGINO2 board (used by Meshpotato v2). Most of the files included can be found in the official svn repository provided by the company [1]. I have just adapt it to the last OpenWrt trunk revision (Fri Oct 4 10:49:47 2013). 1. http://svn.dragino.com/dragino2 Patchwork: http://patchwork.openwrt.org/patch/4234/ Signed-off-by: Pau Escrich <p4u@dabax.net> [juhosg: - rename and refresh kernel patch, - fix checkpatch warnings in mach-dragino2.c] Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 38587
