Can anyone tell me if it is a bug of the ELDK4.0?

[Denny]

Hi,
 
     I failed to compile the uboot on my 440GP platform, I set the compile switch as "-m440 -mcpu=440",
    
      But the interest thing is when I change the switch to "-m405 -mcpu=440", I can compile my uboot successfully, why?
 
      Also I find all the instructions are existed both in user manual of PPC_405 and PPC440.
