    thanks for the explanation.

    So have your "fix" configuration and a few overlays you switch at
    runtime. The problem you have is that you want to switch a specific part
    if your configuration at runtime. I assume you run DT on ARM. What
    happens if you swtich from ARM to x86 and you "keep" your FPGA
    configuration requirement? You can't use both, DT and ACPI, right? So
    what happens then?
