AM62 StarterKit (SK) board is a low cost, small form factor board designed for TI’s AM625 SoC. It supports the following interfaces: * 2 GB DDR4 RAM * x2 Gigabit Ethernet interfaces capable of working in Switch and MAC mode * x1 HDMI Port with audio + x1 OLDI/LVDS Display interface for Dual Display * x1 Headphone Jack * x1 USB2.0 Hub with two Type A host and x1 USB Type-C DRP Port * x1 UHS-1 capable µSD card slot * 2.4/5 GHz WLAN + Bluetooth 4.2 through WL1837 * 512 Mbit OSPI flash * x4 UART through UART-USB bridge * XDS110 for onboard JTAG debug using USB * Temperature sensors, user push buttons and LEDs * 40-pin User Expansion Connector * 24-pin header for peripherals in MCU island (I2C, UART, SPI, IO) * 20-pin header for Programmable Realtime Unit (PRU) IO pins * 15-pin CSI header Add basic support for AM62-SK. To keep the changes to minimum. Only UART And SD are supported at the moment. This should serve as good example for adding new board support based on AM62x SoC Schematics: https://www.ti.com/lit/zip/sprr448 Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Aswath Govindraju <a-govindraju@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Dave Gerlach <d-gerlach@ti.com> Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com>
