What hardware did this happen on? If it was on ARMv5, adding the packed attribute is probably the correct fix. If it was ARMv6 or later, something else is broken as well.
It does not matter if this was ARMv6+ hardware or not. The current U-Boot code is wrong and we need to fix it.
The question is how many errors there are. That's why I asked about the hardware.
I've seen it on a number of devices but they were all ARMv7+ (AllWinner, Rockchips etc)
It was on an Allwinner SoCs with a Cortex-A7 CPU, so armv7. However, as far as I know, the unaligned accesses are disable in u-boot.
Yes, so it seems, although I can't fathom why.
