Because dfl.c uses the 'devm_ioremap', 'devm_iounmap',
'devm_ioremap_resource', and 'devm_platform_ioremap_resource'
functions, it should depend on HAS_IOMEM.

This fixes make allyesconfig under UML (ARCH=um), which doesn't provide
HAS_IOMEM.

Do you think we can add a Fixes: tag for this?

Sure. I think it should be:

Fixes: 543be3d ("fpga: add device feature list support")

Let me know if you want me to re-send the patch with that included.

I think it should be:

Fixes: 89eb35e810a8 ("fpga: dfl: map feature mmio resources in their own feature drivers")
