ufs-exynos driver enables the shareability option for gs101 which means the descriptors need to be allocated as cacheable.

Shouldn't that code be modified such that the shareability option is only set if the dma-coherent property is present in the device tree?

That's what we do downstream and would fix any issues when booting with an older DT that doesn't have the `dma-coherent` property set. So I agree that would be a worthy fix (which I did verify fixes the stability issues).
