We have some KUnit tests for ASoC but they're not being run as much as they should be since ASoC isn't enabled in the configs used by default with KUnit and in the case of the topology tests there is no way to enable them without enabling drivers that use them. This series provides a Kconfig option which KUnit can use directly rather than worry about drivers.
Further, since KUnit is typically run in UML but ALSA prevents build with UML we need to remove that Kconfig conflict. As far as I can tell the motiviation for this is that many ALSA drivers use iomem APIs which are not available under UML and it's more trouble than it's worth to go through and add per driver dependencies. In order to avoid these issues we also provide stubs for these APIs so there are no build time issues if a driver relies on iomem but does not depend on it. With these stubs I am able to build all the sound drivers available in a UML defconfig (UML allmodconfig appears to have substantial other issues in a quick test).
With this series I am able to run the topology KUnit tests as part of a kunit --alltests run.

Changes in v2:
- Add support for building ALSA with UML.
- Link to v1: https://lore.kernel.org/r/20230712-asoc-topology-kunit-enable-v1-0-b9f2da9dc...
Mark Brown (5): driver core: Provide stubs for !IOMEM builds platform: Provide stubs for !HAS_IOMEM builds ALSA: Enable build with UML kunit: Enable ASoC in all_tests.config ASoC: topology: Add explicit build option
Those look like sensible changes.
