liteSOM is a System On Module (http://grinn-global.com/litesom/). It can't exists on its own, but will be used as part of other boards. Hardware specification: * NXP i.MX6UL processor * 256M or 512M DDR3 memory * optional eMMC (uSDHC2) Here we treat SOM similar to SOC, so we place it inside arch/arm/mach-* directory and make it possible to reuse initialization code (i.e. DDR, eMMC init) for all boards that use it.
