Thanks for testing on your board. I have exynos5422 and exynos5433.(One is eMMC5.0, other is eMMC5.1)
I want to see that it's working fine on my board.
I should miss something..so i will check more detail after complete my other job, or on this weekend.
(It failed for hs400 tuning sequence..I needs to check that it has the board dependency)

Best Regards,
