Well, there is neither a "sep4020" CPU in current mainline U-Boot, nor is there some vendor directory "zx" nor a "BoardOne" board directory. Actually, there is not even a "cpu/" directory in curent U-Boot - this was dropped a long time ago.
here we can see that path of start.o is :arch/arm/cpu/sep4020/ so why the path has been changed into cup/sep4020 and arm-linux-ld give me an error "cannot open cpu/sep4020/start.o: No such file or directory?"
We cannot comment on the bugs in your out-of-tree port as we neverhad a chance to review your changes.
Best regards,
