As the Raspberry Pi has a quite powerful CPU already, I would suggest replacing the or1k with a SPI (or something similar) to Wishbone bridge to let the raspberry pi access all the peripherals we support in ORPSoC. It's a quite small FPGA, so removing or1200/mor1kx would also free up more space for other interfaces. Also, ORPSoC doesn't currently support the Lattice toolchain, but that would be a nice addition if someone was willing to do it. Probably not very hard as long as they have a CLI workflow for Linux //Olof
