I think windows ARM laptops use UEFI?

  They do, Windows Phone even use UEFI (not sure was completely compliant) back in the day.

  publicmail was asking about ACPI vs DT, not UEFI. Using UEFI and ACPI/DT are orthogonal; DT-using devices can also boot from UEFI if the firmware provides it. See https://github.com/TravMurav/dtbloader https://github.com/TravMurav/dtbloader for example.

    This is explicitly what we're doing in RHEL with the P550. We use u-boot and it's EFI capabilities to init grub (instead of another instance of u-boot)

      Why not use systemd-boot?

  looks like they still require a custom device tree to boot Linux
