At least a few years ago while > porting nandsim to UML I found s390 that lacks of io mem too. s390 gained IOMEM support when they started having PCI attachments. arch/score selects NO_IOMEM, though they do in fact use MMIO, and I'm sure their architecture has lots of other problems with build testing that nobody cares about. arch/tile can select NO_IOMEM when PCI is disabled, they might care about this, though I think they also have other build-time issues. > Maybe we depend COMPILE_TEST on HAS_IOMEM? That sounds fine with me as well.
