For me, if only uml left, I suggest to implement dummy functions within
uml instead of let CONFIG_UML appear in generic include directory. And
then remove all HAS_IOMEM and NO_IOMEM from kernel.

If score sticks to NO_IOMEM, and can not remove score from kernel only
because of this reason. I also suggest implement dummy functions within
score itself.


Thanks.
