-----Original Message----- From: kenneth johansson [mailto:kenneth@southpole.se] I had this misconception that the GOT was all that was needed for relocation. Could not find any useful information on what rules apply to gcc and binutils for handling stuff in this fixup section.

Anybody have any information on this?

Nope, never found anything either. To see a working one in u-boot, look at mpc83xx start.S and its linker scripts.

Found some code from gcc that do the relocation in the same way we want in u-boot.

http://gcc.gnu.org/viewcvs/trunk/gcc/config/rs6000/eabi.asm?revision=130805&...

I tried to call __eabi and link with libgcc plus ecrti.o, ecrtn.o but in the end I had one silly undefined symbol(.Lfini) that I could not get past the linker.

But I think copying that code over into u-boot could not hurt. And considering the age of that code I can't imagine that anybody has a tool chain that can't handle using the -mrelocatable. It would be nice to remove the manual relocation done when it's not needed it is just confusing.
