On eMMC devices, the UFS clocks aren't started in the bootloader (or well, at least it should not be, as that would just leak power..), which results in platform reboots when trying to access the unclocked UFS hardware, which unfortunately happens on each and every boot, as interconnect calls sync_state and goes over each and every path.
