I am trying to bring up Linux on a custom MPC870 Board using ELDK 3.0.
Why are you using old (not to say ancient) tools?
The ported kernel from ELDK 3.0 hangs (loops in idled()) and the kernel_thread init never gets started!???
How do you know that init didn't run? Runningthe idle loop is a perfectly normal situation.

Are you sure that your kernel configuration is sensible? For example, did you configure a console port that matches your hardware? Did you configure the serial ports (SMC / SCC) at all?
