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?
