Initially, FdtDxe used an internal (embedded in UEFI) FDT, because it was neither understood how to consume the one loaded by the VideoCore firmware, nor understood just how important it is to use the DTB provided by config.txt. Embedding the DT was a bad idea, because: - Permanently stale - No overlays Also, on devices like the Pi 4 you _have_ to have a DT around for the start4 VPU firmware to pick up, otherwise the board is left in an inconsistent state. So we're being prescriptive now about DT use with config.txt, which means this internal DT logic is dead code. Further FdtDxe cleanups are possible and will be handled separately, specifically: - probably no need to use a separate allocation for patched DT (optimize memory used) - suspicious use of EfiBootServicesData (I filed [0] to sort out the real requirements) Testing: Booted Ubuntu 18.04 on Pi 2B (1.2).
