This is new System-On-Module platform with universal dimm socket for easy insertation. The EVB board is designed to be universal with future modules. Product page is located here [1]. There are two dts files - one for base model and another for eMMC variant. Base features of A20-SOM204 board includes: * 1GB DDR3 RAM * AXP209 PMU * KSZ9031 Gigabit PHY * AT24C16 EEPROM * Status LED * LCD connector * GPIO connector There will be variants with the following options: * Second LAN8710A Megabit PHY * 16MB SPI Flash memory * eMMC card * ATECC508 crypto device The EVB board has: * Debug UART * MicroSD card connector * USB-OTG connector * Two USB host * RTL8723BS WiFi/BT combo * IrDA transceiver/receiver * HDMI connector * VGA connector * Megabit ethernet transceiver * Gigabit ethernet transceiver * SATA connector * CAN driver * CSI camera * MIC and HP connectors * PCIe x4 connector * USB3 connector * Two UEXT connectors * Two user LEDs Some of the features are multiplexed and cannot be used the same time: CAN and Megabit PHY. Others are not usable with A20 SoC: PCIe and USB3.
