Subject: [PATCH 1/2] ARM: imx6ul: Add support for liteSOM
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.

+How to use U-Boot on Grinn's liteBoard
+--------------------------------------
+
+- Build U-Boot for liteBoard:
+
+$ make mrproper
+$ make liteboard_defconfig
+$ make
+
+This will generate the SPL image called SPL and the u-boot.img.
+
+- Flash the SPL image into the micro SD card:
+
+sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
+
+- Flash the u-boot.img image into the micro SD card:
+
+sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
+
+- Jumper settings:
+
+S1: 0 1 0 1 1 1
+
+where 0 means bottom position and 1 means top position (from the
+switch label numbers reference).
+
+- Insert the micro SD card in the board.
+
+- Connect USB cable between liteBoard and the PC for the power and console.
+
+- U-Boot messages should come up.
