After early text debugging is disabled and the correct "console=ttyS0,
115200" option is passed to kernel, the problem still exists. Also I'm
sure the divisor set to UART is also correct because they are the same
values when U-Boot sets up the port.

Has the serial port enabled interrupt so far at this stage?
