We didn't include relocation records in nios2 binary image, so there is
no real relocation like that of ARM.
Can we add them instead ?
I think it is possible. I recalled that we have an old flat image format
with elf2flt to run nonmmu uclinux, which does a similar relocation. But
I would suggest that we should keep thing simple and small in a boot
loader like U-Boot.
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.
Hm, Im not using the Altera loader :)
Neither am I. Look like we all use custom boot copiers, and we don't
need the relocation in the patch above. It doesn't make sense to copy
the code twice. Right? :)
Best regards
Thomas Chou
