We didn't include relocation records in nios2 binary image, so there is 
no real relocation like that of ARM.

Altera provides small boot loaders for cfi/sf along with their nios2 
jtag flash programmer, which will load the image to the linked address 
in sdram. The relocating loop in start.S works only if such Altera boot 
loader is not used, ie, booting directly from cfi flash.

Best regards,
Thomas Chou
