Please don't post HTML, use plain text.

I don't understand your question, why are you asking it?  Are you trying 
to figure out a problem or are you just trying to understand the linking 
processes?

Using objdump on u-boot.bin is not valid.  U-boot.bin is a binary file, 
objdump works on ELF (linker formatted) files.

<http://en.wikipedia.org/wiki/Executable_and_Linkable_Format>

When you link the ELF files, the linker fixes up all the addresses so 
the linker sets the proper address in the instruction that the CPU 
ultimately executes.  The u-boot.bin file is a raw binary dump of the 
result.

Was that your question???
