Key areas where platform firmware developers must go beyond the scope of SystemReady to meet automotive-specific needs.
Automotive platforms can significantly benefit from adopting the Arm SystemReady Devicetree Band as the basis for their platform firmware. By aligning with the SystemReady Devicetree Band and the recommended optional features in this document, platforms can support use cases such as secure boot and update, hardware discovery, power-state coordination, hardware fault detection, and system-level operating modes for specific driving scenarios. SystemReady compliance brings consistency and predictability to the interface between platform firmware and operating systems, helping to reduce integration costs and improve software portability across different hardware implementations. The open-source Architecture Compliance Suite (ACS) provides a practical mechanism for verifying compliance throughout the supply chain, supporting both platform developers and downstream consumers of the technology. The open-source Arm Automotive Solutions Software Reference Stack provides an example of an implementation that complies with the SystemReady Devicetree Band.
