:) Think also that if I'm not mistaken, the GOT has to move to RAM while the .rel.dyn and .dynsym tables will not be necessary once relocated (unless you want u-boot to be able to move around in RAM), so RAM footprint would be smaller. >> bytes since reloc fixup functions in board_init_r would not be needed >> any more. > > Sounds good.
