  "approach": "Looking at the error message \"TypeError: Config.__init__() got an unexpected keyword argument 'devicetree'\", it's clear we need to add a `devicetree` field to the Config class. From the JSON test spec, I can see the expected format includes:\n\n\"Devicetree\": \"freescale/imx8mm-verdin-nonwifi-dev.dtb\",\n\nThis matches the pattern used elsewhere in the codebase where fields appear as PascalCase in JSON but snake_case in Python (e.g., \"BuildScripts\" maps to build_scripts). So I'll add a `devicetree: Optional[Path] = None` field to the Config dataclass in mkosi/config.py. This follows the established pattern shown in other similar optional path fields like linux: Optional[Path] = None.\n\nThe change should be minimal - just adding the field definition to match what the tests expect.",
