ARM: dts: am335x: Add initial support for ICEv2 board TI's Industrial Communication Engine EVM is a low cost hardware mainly developed for industrial communication type applications using serial or Ethernet based interfaces. This platform features TI's AM3359 with 800MHz single core Cortex-A8 processor, 256MB DDR3, 64MB SPI flash, 8MB NOR Flash, mmc, usb, can, dual Ethernet ports. For more information, look at HW user guide[1], Data manual[2]. Just add basic support for the moment.
