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???
