 * Board peripheral code name passed through a "mux="

 * This can be used to differently configure the platform
 * devices, e.g. switch gpio numbers, drivers etc.
 * mainly this is used to differentiate between GTA04
 * GTA04b2 (Letux 3704), GTA04b3 (Letux 7004) etc. and

 * So this is sort of a "major board version" name

 * Maybe we can replace this functionality with different
