"-mno-unaligned-access" works around misaligned data on the software level, while allowing unaligned access does on the hardware level.
What we really want is no unaligned access in U-Boot at all. Just because "-mno-unaligned-access" is the default on ARMv5, we should not consider it a gold standard.
