I do not have to apply your patch. But I expect that wd will only except clean 'splipping' patches.

So it would be better to fix up your tree so that you can generate a patch as it is expected.
If nothing helps, check out a clean U-boot tree, modify it and try it again. 
It should be easier to fix your toolchain (we the help of others) than to get unclean patches
