I see...I think we have a very similar setup, and I see how you init your ports. Although I'm not sure if this is suitable for me, since editing the ns16550-files to support/init an external COM-chip is not a really clean/nice implementation.
I'm not sure if there is any way to implement this in a nice way. But I will let you know if we find something ;)
I implemented it first in board specific code. It added small code overhead due to necessity to duplicate the serial_ports array and add uart_init for ports higher then 4. Afterwards, I implemented the same in common code. Extending the original serial_ports array makes the code more generic. I also added serial loopback tests availible via CLI and POST. I am going to post this patch on u-boot-list promptly.
