Subject: Device Description for FPGA Components on x86 system

Hello,

I'm looking for guidance

What I have:
* Intel x86_64 computer
* PCIe card with FPGA on it

What I want to achieve:
* load an FPGA bitstream on the card
* load a device-tree like description for the FPGA devices contained in the 
bitstream

This is achievable on ARM with DeviceTree, overlay-dt, fpga-mgr; but I'm 
puzzled about the x86_64 use-case. I'm not able to find recent and clear 
information.

Does anyone know if this is doable? Perhaps with ACPI SSDTs overlay? Or with 
the DT?

thanks
