Once the reloc branch has been merged, how many arches are left which do not support relocation?
All but PPC ?
Hmm, so commit 0630535e2d062dd73c1ceca5c6125c86d1127a49 is all about removing code that is not used because these arches do not do any relocation at all?
I sent that patch/RFC after noticing none of those architectures performed manual relocation fixups, thus they could save some code space by defining CONFIG_RELOC_FIXUP_WORKS. Similarly the gd->reloc_off field was no longer needed for them.
I'm not familiar with if or how those architectures are relocating, just that they didn't need relocation fixups. So that was the logic...
the usage in the Blackfin port is most likely a copy & paste of existing code. deleting malloc_bin_reloc() from lib_blackfin/board.c and adding CONFIG_RELOC_FIXUP_WORKS results in a working boot. ive never really looked into relocation as no one has asked for it. -mike
