Good question, do you have both ports working in Linux yet? The EVM-SK
design supports two interfaces and I know the cpsw driver in the kernel
required some changes to support two. I strongly suspect similar
changes would be required in the U-Boot driver (I don't have any
specific links other than look at the vendor kernel tree).
