Hence it could have a fully functional s390 kernel with CONFIG_PCI=n, then the relevant iomem mapping functions [including ioremap(), devm_ioremap(), etc.] are not available. Here let FSL_EDMA and INTEL_IDMA64 depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset. -------- ERROR: modpost: "devm_platform_ioremap_resource" [drivers/dma/fsl-edma.ko] undefined!
