You have a LARGE hole in your memory map (something is linked at the 
start of memory and something is linked at the end of memory) and 
objdump is merrily filling it with 0xFF.  You are probably creating a 
4GB output file that is nearly all 0xFF.

Use ${CROSS_COMPILE}objdump -h on your .elf file to see where things are 
located, then fix your memory map.
