Hi,
We are porting u-boot on our card. We have take SBC board as reference and changed the code from that board's code. In the process, we got stuck-up with a problem of relocating the code. Please see the following dump. We are loading the code through emulator into the ram at address 0x00000000.

The bus fault location @3388 corresponds to the function "relocate_code" from objdump. The header file of the card is attached to this mail.
Please let us know if you can identify any problem with the header file.
