Hi Wolfgang,

I'm not sure if this patch could work for not PowerPC based 
architectures. Taking a look in the U-Boot starting files for mips and 
bf533 cpu's, it seems that only the GOT section is relocated in ram, so 
the patch probably won't work. Furthermore, there is some fpga's 
relocations that I can't understand, and I don't know what is the effect 
of my patch for boards with a fpga. I mean I can't supply a patch valid 
for all architectures without doing some bugs.

I think the method I suggest you using a new define It's quite 
reasonable. I'll summit the patch for the Lite5200's and the rest of 
boards will be not affected. If someone want to use or test the fixup 
relocation for his board only has to do two changes:
            - cleanup the fixup section from the text section in  the 
u-boot.lds file.
            - define CFG_FIXUP_RELOCATION in the board configuration file.

I believe this is the safest way to do it. What do you think?

Best regards,
