System DT summary from 3/25
* AMD adoption and tooling:
* AMD has fully integrated System DT into its Yocto flow for an upcoming release, enabling configuration defined once in System DT to flow automatically to each OS or subsystem through Yocto or similar build infrastructure.
* OS and platform support:
* AMD can generate Devicetree for Zephyr alongside Linux as part of the OpenAMP multi‑services work.
* Upcoming releases will build Zephyr inside Yocto (instead of West) and generate #defines for bare‑metal.
* Initial focus is on platforms newer than ZynqMP, with ZynqMP needing follow‑up support.
* Rollout approach:
* System DT examples were not previously included due to lack of public System DT databases for boards (so would have needed AMD tools to generate) and an evolving specification.
* Now that these are public, documentation will start with Baremetal and FreeRTOS, with Zephyr and ZynqMP planned later.
* Baremetal and FreeRTOS are expected to be more vendor‑specific than Zephyr.
* Broader adoption and standardization:
* VxWorks support is of interest since it can consume Devicetree, and deriving a VxWorks DT from System DT could benefit many AMD customers who use VxWorks.
* Emphasis is placed on keeping DT and System DT standardized, even if different vendors use different generation tools.
* Lopper is being explored, including for hypervisor use cases such as Xen, and broader vendor feedback is encouraged to help System DT mature into an industry standard.
