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 francesco.monte@gmail.com: https://github.com/fmntf/u-boot/commit/877b71184a5105e708024f232d36aed574961...

Only tested on the UDOO Neo Full board.
