mx31moboard: initial support for various baseboards
This enables our mx31moboard to be used on the different baseboards that we are developping according to the application needs. There are not many differences between the boards for now, but when other peripherals are available for mx31 the differences are going to grow. v2: takes Sascha's comments into account Signed-off-by: Valentin Longchamp <valentin.longchamp@epfl.ch> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
