... which has the same register layout (well, at least that ones you
need in u-boot) as the other ones. The basic serial support in
cpu/arm920t/imx_serial.c (well, not exactly a good place for a serial
driver, but that's how it was done for the other ports) can easily be
extended to support more than two serial ports.

Attached. I'm not sure about the memory situation on the ADS board, our
board has 32 Bit flash.
