You shouldn't just change an existing board configuration but port U-Boot to 
your board. In nearly all cases the differences to the eval boards are too 
big to just change things in the eval board files. And you have no chance of 
upstream acceptance this way.

This should do what you need. Add this to your board config header:

#define CONFIG_UART1_CONSOLE
