VMARC RK3288 SOM is a standard SMARC SOM design with Rockchip RK3288 SoC, which is designed by Vamrs.
Specification: - Rockchip RK3288 - PMIC: RK808 - eMMC: 16GB/32GB/64GB - SD slot - 2xUSB-2.0, 1xUSB3.0 - USB-C for power supply - Ethernet - HDMI, MIPI-DSI/CSI, eDP
Add initial support for VMARC RK3288 SOM, this would use with associated carrier board.
