Nak. Don't hide a null pointer. NULL pointers are *not* relocated, since they are a constant. If a NULL ends up in relocation tables, that is because of a corruption *or* because it was to be relocated, and should thus never be ignored.
Depends, if the same routine is used for relocating fixups you need this test.
Undefined weaks will generate a NULL fixup entry.
As mentioned by Jens and one other some time ago. Albert, please build e.g. at91rm9200ek boards and search for board_reset(), defined in arch/arm/cpu/arm920t/at91/reset.c
