All,
 
MPC83xx data cache locked all ways in u-boot. This means data cache looks like cache-inhibit. when kernel run at this u-boot, kernel don't unlock data cache, so the data cache actually run at inhibited state. I suggest we need unlock data cache after relocate_code in start.S file.
 
If unlock data cache in start.S file, we need change everything, such as BATs settings and DDR ECC test code. I have found some bugs in ECC test code.
 
Regards,
Dave
