That depends. If your UEFI firmware provides ACPI, then that is
responsible for doing the hardware description and low-level
platform initialization.

But there are systems with UEFI and no ACPI that then pass a
regular DTB to the operating system.

Our UEFI bootloader creates a fake DTB when it gets information
about ACPI being in charge and the kernel uses the ACPI attachments
instead of fdt or platform attachments.
