problem on MPC8xx

[LiuTao]

Hi:

I am debugging Linux on my customized board.
The messages in log_buf are all right. The shell in RAM disk
also runs. But I can't see anything on serial port.
I want to know:
1. May I use ramdisk.image.gz of mbx as my ramdisk?
2. Need I modify the uart.c? If I need, which part I should modify?
3. Is there any meathod to test if the serial port is OK?

Thanks!
