This patch is needed to allow arm to use the generic drivers/Kconfig file. Introducing HAVE_IDE so each arch explicit select HAVE_IDE if supported allowed us to get rid of HAS_IOMEM which is anyway overloaded. And doing it this way is a much better way to document which architectures that supports IDE. Furthermore the decision if IDE is supported or not is distributed. Consider seeing this all over: -if PCMCIA || ARCH_CLPS7500 || ARCH_IOP32X || ARCH_IOP33X || ARCH_IXP4XX \ - || ARCH_L7200 || ARCH_LH7A40X || ARCH_PXA || ARCH_RPC \ - || ARCH_S3C2410 || ARCH_SA1100 || ARCH_SHARK || FOOTBRIDGE \ - || ARCH_IXP23XX source "drivers/ide/Kconfig" -endif Only s390 and um does not support IDE from my quick investigation, if there are others let me know. [Added linux-arch to catch all arch maintainers]. Comments?

All archs except arm, um and s390 unconditionally select it. For arm the actual configuration determine if IDE is supported.
