Code above is aligned with previous support but I can't see that macro in Kconfig.
Also it is kind of weird that on arm you can run i386 image. It could be stopped later but that changes just suggest that this should be changed.
Thanks,
Michal

It's the generic area where we make sure either the image is for what we're running on, or the special cases, ie aarch64 runs arm or x8664 runs i386 :)
