From 792f186846672140deca7dfbf2f20aece26b5348 Mon Sep 17 00:00:00 2001 From: Breno Lima Date: Fri, 25 Nov 2016 16:56:57 -0200 Subject: [PATCH] mx6sx: Add initial support for UDOO Neo Board UDOO Neo Board is a development board from Seco that has three models: - UDOO Neo Basic - UDOO Neo Basic Kick Starter - UDOO Neo Extended - UDOO Neo Full All versions are based on the i.MX6 SoloX processor. For more details about the UDOO Neo board, please refer to: http://www.udoo.org/udoo-neo/ This work is based on a previous commit of Francesco Montefoschi : https://github.com/fmntf/u-boot/commit/877b71184a5105e708024f232d36aed574961844 Only tested on the UDOO Neo Full board.
