I know exactly what Grant did. But he is not using the elf relocation information as that is simply not included in the data that is the u-boot.bin file.
So what? Is this a problem? Why would we need to use XXX if we can perform all we need to do by using YYY instead, especially if this is simpler to implement?
Also this discussion is more about doing it in a way that is not powerpc specific and documented, we already have as you mentioned code for the powerpc specific way but it's not using elf relocation information.
Who says that we MUST use the ELF reloc info?
Or why?
I was afraid that what was needed was more or less a complete linker but it looks like if one generate the dynamic reloc table a much simpler linker(relocation function) is needed. Still probably a lot more complex than the GOT and fixup code that is just a loop over a table. We may need a case also ;-)
Please re-read Grant's patch. There were NO changes to the existing simple code!
