Only now it becomes clear that you are not talking about Linux at all.
Your posting is off topic in the linuxppc-embedded mailing list.
Chances for useful replies are much better in the u-boot-users
mailing list instead.
Chances for useful replies would be even better if you provided a
little more information. "modify several line of ..." is not really a
precise description of what you did.
Porting U-Boot to new hardware requires more than just tweaking a
line here and there. It will require both an in-depth understanding
of the hardware and U-Boot.

Did you read the README that comes with U-Boot?
Finally: did you order your BDI2000 yet? You will probably need it
soon.
Best regards,

If all you have is a hammer, everything looks like a nail.
