The SK architecture comprises of baseboard and a SOM board. The AM68 Starter Kit's baseboard contains most of the actual connectors, power supply etc. The System on Module (SoM) is plugged on to the base board. Therefore, add support for peripherals brought out in the base board. Schematics: https://www.ti.com/lit/zip/SPRR463 Signed-off-by: Sinthu Raja <sinthu.raja@ti.com>
