As a general comment, this is the same file that RedBoot uses - it's lattice code, so I didn't do much with it. Yes the formatting is pretty horrible. And the comments are pretty misleading.
It is needed, the kernel expects the FPGA to be already programmed & ready to go, there is no code to handle FPGA loading in the kernel.
The whole point of this is to have u-boot to be a drop in replacement for RedBoot, providing backwards compatibility with kernels & images created for RedBoot.
Best regards,

If it's any consolation, I have the same problem getting Xilinx-derived code accepted into U-Boot. :)
