you use a very old version of u-boot, you should update to current
version.

As the error message says, some symbols are missing ... if you want to
use i2c, you must enable through a CONFIG option, which i2c driver you
want to use on your hardware. I cannot help you more here, because I
do not know anything about your board.

Yep!
