This makes no sense. The serial driver is already included  with  the
U-Boot running on your board, so you don't need it in your standalone

This makes no sense. The driver is already initialized and running in
the U-Boot context. What are you trying to do?

I don't think so. The hello_world example does not perform  any  such
funny stuff.

Seems your linker options are not OK...

You get these problems because you obviously did not understand how a
standalone application works. But you don't provide  enough  informa-
tion to come up with more detailed advice.
