More effort then producing unique images for every board?
- Arnavion 1y agoYes. See https://github.com/aarch64-laptops/edk2/tree/dtbloader-app?tab=readme-ov-file#why-not-acpi https://github.com/aarch64-laptops/edk2/tree/dtbloader-app?t... for example.
- ChocolateGod 1y agoIt's a shame the DT approach encourages land fill of boards when the manufacturer stops providing updates.
- Arnavion 1y agoNot necessarily. DT can be loaded separately from u-boot tree / kernel tree / dtoverlay file.
- mappu 1y agoThe DT should really be put in the firmware (e.g u-boot), same as ACPI on x86 is in the firmware (the bios/efi). Then you wouldn't need a unique kernel/OS image. For devices that have u-boot in ROM the DT is usually there (fdt).
