v2 cover Add support for sbc-t43

This series adds support for CompuLab sbc-t43 single baseboard computer. sbc-t43 is composed of cm-t43 (the TI am437x based core module), and sb-som baseboard. The sbc-t43 features include:

CPU: Texas Instruments Sitara AM4379 ARM Cortex-A9, 1GHz, or
Texas Instruments Sitara AM4376 ARM Cortex-A9, 800MHz

RAM:    128MB - 1GB, DDR3-800, 32-bit data bua
Storage:        NAND flash, 128MB - 512MB, or eMMC flash, 4GB - 32GB

SPI-flash 2MB
Two 1000/100/10Mbps Ethernet ports
WiFi/Bluetooth/NFC
Audio codec
SD-Card slot, up to 3 USB ports
DVI/LCD connectors

PATCH v2 1/14 ARM: dts: am437x: cm-t43: add basic support for sbc-t43

Add basic support for SBC-T43: a CM-T43 based single board computer. CM-T43 is an AM437x based System-on-Module designed to serve as a building block in embedded applications. SBC-T43 is composed of CM-T43 module on top of the SB-SOM-T43 baseboard.
Basic support includes UART, GPIO, and I2C.
