[U-Boot] MPC8641D stucks before relocation

[York Sun <yorksun@freescale.com>]

You said you used the exactly same register for CodeWarrior and U-boot.
CodeWarrior works but U-boot doesn't? You can try two methods to debug.

1) Build a RAMBOOT u-boot, use CodeWarrior to initialize DDR and copy
u-boot to its destination and start to run.

2) Let u-boot initialize DDR, make a inf loop. Use CodeWarrior to
"attach" to it and stop the core, check registers and memory access.
