I don't think it hurts to have a generic function with ARM errata workaround implementation. Whoever wish to use it can call it in their boot path. And it's not even getting executed right now for any SoC other than Exynos542x, so those who don't want it need not bother about it. This was the intention. :)

What about exynos542x platforms which also have secure firmware? Are you testing this on any of those (e.g. exynos5422-odroid-xu3?)

No, I have not tested this series on exynos5422-odroid-xu3 becuase I don't have it. :)

Probably those who are working on exynos5422-odroid-xu3 should comment. I don't know anything about exynos5422-odroid-xu3 and don't have related documents. But as far as I know, from my past experience, for all such features (SMC calls, secondary cores boot path and configuration), there should be a different secure firmware which may not be U-Boot. If true, this whole series of patches would be useless and CONFIG_EXYNOS5420 should not be defined for such a SoC.
