Running linux on MPC860

Hi all,

I am trying to bring up a mpc860 based board. There are some progresses that that i have made and some remaining. Could anybody help me out on the rest. What I am able to do with the board.

1. I am able to communicate to the board using MPCBDM. Able to read write registers. Dump memory etc.
2. I have setup a cross tool chain for MPC860 and able to compile the linux kernel using it to build. zImage.embedded and zImage.initrd.embedded.
3. I am able to download these images on the board.

This is where i am stuck.

I am not able to boot the kernel. I am manually coded the bd_info structure in embed_config.c with my board details. Like ram base address/size cpu/bus frequency.

I am not very sure how to point the kernel to the root file system. I mean if i have the root file system and the kernel image how do i start the system.

Any pointers as how to go ahead from here will be of great help.

Thanks in advance Pritam
