It's either a DTB per device or a firmware blob per device. I'll take the open source device tree anytime!

  A DTB is a blob. Whether you have the source is a vendor decision, just like ACPI. There's no inherent difference here.

    You can convert a DTB blob back into source code: dtc -I dtb -O dts -o devicetree.dts blob.dtb Big, biiig, biiiiig difference! PS: You can also examine it directly as a directory tree in /sys/firmware/devicetree/*

      You can convert ACPI bytecode back to source with iasl. No difference at all.
      • M95D 8mo ago
        Then you can load them in u-boot and there's no need for any ohter blob.

          Yes, and you can do this with ACPI as well. There's no difference between the inherent freedom of ACPI and Devicetree.
