What's wrong with the existing port? Version 1.1.1 is too old, and existing port works fine for me.

You can't use FEC2 and SMC2 simultaneously, and the factory DIP switch settings select FEC2. Make sure you've got correct settings and enable SMC2 UART in BCSR.

Probably you didn't change BR0/OR0. Anyway, it works in current version of U-Boot. Make sure that you've got updated BCSR, otherwise you have to modify the SIMM because original BCSR does not recognise this SIMM correctly.
