Portting Linux to MPC8247

[yulq at jiaxun.com]

I'm portting Linux to MPC8247 using ELDK-3.0 Kit and U-boot-1.1.4.
The boot and kernel work well. But the console can't print anything.
In /etc/inittab, I append line: s0:2345:respawn:/sbin/mingetty ttyS0 9600
linux.

... ...

Kernel command line: console=ttyS0,9600n8 root=/dev/nfs rw

Where is the problem ? Thanks.
