System Devicetree Support in Zephyr

Explore the system devicetree specification and its role in addressing usability issues in Zephyr's support for AMP SoCs. Learn about the extension of the standard Devicetree Specification, which allows for simultaneous representation of multiple CPU clusters within heterogeneous SoCs, including memory maps, partitions for different executable images, and peripheral assignments. Understand the problems being solved, why current build system infrastructure is insufficient, and how system devicetree can help. Gain insights into the ongoing work to support system devicetree in the Zephyr build system. This 38-minute conference talk by Marti Bolivar from Nordic Semiconductor, presented at a Linux Foundation event, delves into the intricacies of hardware support features in devicetree, hardware model, and build system layers.
