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.
