Basically the driver just wraps the information such as the pixels to be drawn by the FPGA FrameBuffer 2. The piece of hardware in discussion is the SoC FPGA where Linux runs on the ARM chip and the FGPA is driven by its NIOS soft core with its own proprietary firmware. For example the application from the ARM Linux would have to write information on the /dev/fb0 with the information stored in the SDRAM to be fetched by the FPGA framebuffer IP and displayed on the Display Port Monitor.
