Subject: [RFC] Introduce HAVE_IDE to support flexible IDE per arch configuration
Following patch introduce HAVE_IDE to support flexible per
arch or even per. sub-arch configuration of IDE support.
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?

Subject: [PATCH] ide: introduce HAVE_IDE
To allow flexible configuration of IDE introduce HAVE_IDE.
All archs except arm, um and s390 unconditionally select it.
For arm the actual configuration determine if IDE is supported.
