Note that this includes disabling UHS support since SDR50 and above require a Tegra-specific tuning procedure which is not supported yet (and still seems to have issues even in downstream kernels). This depends on the following patches which fix an issue where the eMMC's power supply gets toggled, causing eMMC failures: http://patchwork.ozlabs.org/patch/339386/ http://patchwork.ozlabs.org/patch/339710/ Tested on Tegra124-based Venice2 and Norrin boards.
