Add board support for ICnova A20 SomPi compute module on ICnova ADB4006 development board. Specification: SoM - Processor: Allwinner A20 Cortex-A7 Dual Core at 1GHz - 512MB DDR3 RAM - Fast Ethernet (Phy: Realtek RTL8201CP) ADB4006 - I2C - 2x USB 2.0 - 1x Fast Ethernet port - 1x SATA - 2x buttons (PWRON, Boot) - 2x LEDS - serial console - HDMI - µSD-Card slot - Audio Line-In / Line-Out - GPIO pinheaders https://wiki.in-circuit.de/index.php5?title=ICnova_ADB4006 https://wiki.in-circuit.de/index.php5?title=ICnova_A20_SODIMM --- changes in v2: - use short licensing header - remove deprecated elements from led nodes - disable csi power supply - add missing pins in usbphy node - split dts into SoM dtsi and carrier board dts v1 of this patch was sent to the uboot mailing list [1].
