The PURWA-IOT-SOM is a compact computing module that integrates a System on Chip (SoC) — specifically the x1p42100 — along with essential components optimized for IoT applications. It is designed to be mounted on carrier boards, enabling the development of complete embedded systems. Purwa uses a slightly different Iris HW revision (8.1.2 on Hamoa, 8.1.11 on Purwa). Support will be added later. Make the following peripherals on the SOM enabled: - Regulators on the SOM - Reserved memory regions - PCIe3, PCIe4, PCIe5, PCIe6a - USB0 through USB6 and their PHYs - ADSP, CDSP - Graphic Reviewed-by: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com> Reviewed-by: Abel Vesa <abel.vesa@oss.qualcomm.com> Signed-off-by: Yijie Yang <yijie.yang@oss.qualcomm.com> Link: https://lore.kernel.org/all/20260202073555.1345260-3-yijie.yang@oss.qualcomm.com/
The PURWA-IOT-EVK is an evaluation platform for IoT products, composed of the Purwa IoT SoM and a carrier board. Together, they form a complete embedded system capable of booting to UART. PURWA-IOT-EVK uses the PS8833 as a retimer for USB0, unlike HAMOA-IOT-EVK. Meanwhile, USB0 bypasses the SBU selector FSUSB42.

…e trees All the existing variants Hamoa boards are using Gunyah hypervisor which means that, so far, Linux-based OS could only boot in EL1 on those devices. However, it is possible for us to boot Linux at EL2 on these devices [1]. When running under Gunyah, the remote processor firmware IOMMU streams are controlled by Gunyah. However, without Gunyah, the IOMMU is managed by the consumer of this DeviceTree. Therefore, describe the firmware streams for each remote processor. Add remoteproc IOMMUS to the EL2 device trees to generate the corresponding -el2.dtb files.
