This is a SOM (System on Module), so it will be part of another boards.
Hence, this is a "dtsi" file that will be included from another device
tree files.

Hardware specification:
 * Freescale i.MX6UL SoC
 * up to 512 MB RAM
 * eMMC on uSDHC2

Changes v3 -> v4: none

Changes v2 -> v3:
 * Remove cpu0 supplies (arm-supply, soc-supply), as they were already
   set in imx6ul.dtsi file (reported by Sébastien Szymanski)

Changes v1 -> v2:
 * Use dual license
