The platform consists of a system-on-module (SoM) mounted on a carrier board. The SoM integrates the core system functionality through a SiP containing the X1E80100 SoC and its supporting components. Hierarchy: Carrier Board -> SoM -> SiP -> SoC The COME SiP hardware is effectively the same as the SoM used on the Qualcomm HAMOA EVK, while the carrier board provides the platform-specific peripherals and connectivity. Compared to the HAMOA EVK, PCIe controllers 3, 5 and 6 are routed to expansion slots, while PCIe controller 4 is connected to an ASM1164 SATA controller. The platform does not provide a USB Type-C connector. The eUSB repeater (TUSB2E111YCGR) is configured through hardware strapping pins and therefore requires no software control. The initial device tree includes support for: - UART - Regulators - USB - PCIe - Pinctrl - ADSP, CDSP - UFS - Graphics - Video Regulators, pinctrl, graphics, video, ADSP and CDSP support are inherited from the common hamoa-iot-som.dtsi description.
