The 'commit e25df1205f37 ("[S390] Kconfig: menus with depends on HAS_IOMEM.")'
added the HAS_IOMEM dependecy for "Graphics support". This disabled the
"Graphics support" menu for S390. But if we enable VT layer for S390,
we would also need to enable the dummy console. So let's remove the
HAS_IOMEM dependency.
Move this dependency to Opencores framebuffer driver which would fail to build
with CONFIG_HAS_IOMEM disabled:
ERROR: "devm_ioremap_resource" [drivers/video/fbdev/ocfb.ko] undefined!
"Graphics support" menu covers other things (i.e. DRM), I assume that
they were also checked to not break due to this change?
Yes, DRM compiled fine. And we (s390) would need the DRM subsystem for
Virtio GPU as well.
Moreover it seems that after this change "Graphics support" menu will
be also enabled (besides s390) for score, tile and um architectures,
I assume that this is okay?

This also enables several PCI based graphic device driver on s390.
This makes no sense but they all compile fine so I guess this is ok.
I think patch 2 and 3 are clearly for the s390 tree, patch 1 seems trivial
Also ccing Bart. Can we maybe get an ack to carry this patch also via the s390
tree?
