The behavior supported by this patch is not a hardware bug - my
understanding is that it is behavior that has been chosen on purpose by
the Exynos design team.
I can convert this patch such that it uses a "quirk" flag instead of a
kernel config option to enable support for Exynos encryption. However,
doing that will add runtime overhead in the hot path for all UFS
vendors, including those that are compliant with the UFSHCI
specification. Is everyone OK with this?
Thanks,
Bart.
