This patch adds documentation for Odroid-XU3. This documentation is based on that of Odroid (doc/README-odroid) made by Przemyslaw Marczak. The documentation includes basic information about boot media layout, environment, partition layout, and the instruction to burn the u-boot image to boot media.
