list of supported FPGA with oneAPI

OneAPI requires a BSP similar to OpenCL. Even though OpenCL is supported on Cyclone V and there are some Cyclone V boards out there with OpenCL support (e.g. quite a few of Terasic's boards), I have not seen any Cyclone V boards with OpenAPI support. Intel officially only supports their own PAC boards (Arria 10 and D5005) and custom platforms supporting Quartus 19.4 and above. I know some of Bittware's Stratix 10 boards support OneAPI as well. Other than that, I don't think there are any Cyclone V boards with OpenAPI support right now, and it is unlikely there will ever be one. Intel's system requirements for OneAPI are here:
