I don't think IFC is considered as a required component on all SoCs. The LS1012A does not have IFC.
What does this mean?
But if IFC is not enabled in U-Boot on some boards, accessing IFC memory space would cause kernel call trace. So disable IFC node in such
cases.
That's the symptom, not the problem. The problem is that the kernel is assuming that U-Boot has done certain initialization, such as the chipselect registers, and clearing SRAM (though Linux really should be doing the latter). Why is U-Boot being configured without this?
