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.
