That's exactly what I was looking for. For the ZYNQ it is not implemented yet, but I could use the ZYNQMP as a reference.

Could you give me an example for an OF overlay to load a firmware? Do I have to place the firmware at a specific path like with Linux FPGA manager or can I specify the path in the overlay?
