Unfortunately, all the applications are running on 2.4 kernel. I can not
just throw the 2.4 kernel. I took the some core specific code from
ppc.bkbits.net, such as head_e500.S and mpc85xx_cds_common.c. I assume the
image should work on the 8548 CDS board, or at least for the bootup. I shall
able to have the serial port working in platform_init(). However , the
code stops in the head_e500.S. This does not make any sense. Please correct
me if I am wrong.

BTW, I am using the tool-chain gcc-3_4-e5000glibc-2.3.4-dp, which is from
Freescale for the 8548 CDS BSP of 2.6 kernel.

Any suggest or comment is welcome, I am struggling with this issue for
almost one week...... :-(
