MFD_CORE is selected by MFD_HI6421_SPMI, and MFD_CORE depends on HAS_IOMEM. If HAS_IOMEM is not set, this can cause a conflict in Kconfig resolution, yielding the following error: WARNING: unmet direct dependencies detected for MFD_CORE Depends on [n]: HAS_IOMEM [=n] Selected by [y]: - MFD_HI6421_SPMI [=y] && STAGING [=y] && OF [=y] && SPMI [=y] By specifying HAS_IOMEM as a dependency for MFD_HI6421_SPMI (as SPMI_HISI3670 already dows), this issue is resolved, and no such warning appears when building on architectures without HAS_IOMEM.
