The LiteX SOC controller driver makes use of IOMEM functions like
devm_platform_ioremap_resource(), which are only available if
CONFIG_HAS_IOMEM is defined.
This causes the driver not to be enable under make ARCH=um allyesconfig,
even though it won't build.
By adding a dependency on HAS_IOMEM, the driver will not be enabled on
architectures which don't support it.

Is this wording correct? I suspect it causes to driver TO BE enabled.

This looks ok to me. I can queue it for 5.11 fixes, if you can help with the
wording above.

Whoops! Yes: that should be "causes the driver to be enabled" -- sorry
about that.
Let me know if you want me to re-send it with the fixed wording, or if
you just want to fix that yourself.
