Subject[PATCH] MTD: Refine HAS_IOMEM dependency
Date
Making the entire mtd subsystem depend on HAS_IOMEM is a bit overkill.
HAS_IOMEM is only needed for real devices drivers.
nandsim and friends are perfectly usable on systems without IO memory.

I'm my case I'm using nandsim on UML to do some UBI and JFFS2 development.
