[U-Boot] Question regarding FPGA firmware load in u-boot

Hello List,

I want to boot a (Lattice) FPGA from u-boot by using Slave Serial configuration on a Marvell Kirkwood device. 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? It seems I have to create a image with mkimage? This image have to be loaded into ram and the address has to be provided to the load command? 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!

Thanks to all, Dieter
