Should be no problem as long as you'll have access to GPIO. > As seen there is an (Xilinx and Altera) FPGA loader driver allready available > in u-boot. > Please can somebody explain how I have to provide a FPGA bitstream > image to u-boot? The easiest way is to reserve some unused flash sectors and use the first sector's start adress as arg for "fpga load". > It seems I have to create a image with mkimage? no - Lattice specififc bitstream can be stored in raw format. mkimage may be useful for update, but personally I prefer update via dedicated linux mtd partition. > This image have to be loaded into ram and the address has to be provided to > the load command? Usually an FPGA is *very* board specific. I'd suggest to use flash and create a corresponding mtd partition for linux, i.e. make it maintainable. > Is there a maintainer for the FPGA code inside u-boot? > I'm willing to contribute some extensions for Lattice FPGAs if I'm successful! excellent - all you'll need is the Lattice specific bit toggle sequence. submitting a proper patch will surely do.
