Nothing is loaded into the FPGA, but you can obtain all of the sample projects
for MCV from https://gitlab.denx.de/marex/mcvevk.git .

The FPGA is unprogrammed, you need to load it with a RBF file from U-Boot using
the "fpga" command or using /dev/fpga* interface from Linux. You can also use
the USB blaster and load the FPGA from Quartus programmer.

btw feel free to poke me directly if you have further questions.
