I was able to fix the API compile issue but what is missing is a feature I really want which is u-boot automatically loading the PL (FPGA fabric) from “fpga.bin”.  I’ve been working on a video driver which can only work if the PL/FPGA design is loaded before the kernel is booted.  I tried to enable this feature in both your u-boot tree and the official repository and it fails to link the spl stage in both cases.

I’d like to submit these ports as I have them, based upon Xilinx’s u-boot tree at github.com/Xilinx/u-boot-xlnx.  It works great with only a simple patch.  I’d submit them via the bug system as described in the porter’s handbook.

What do you think?
