Jaehoon,
The latest commit in u-boot-mmc.git master branch fails on almost every
Tegra board. The MMC device experiences an error during initialization
and hence isn't available:

Thanks for reporting this. I'm not sure but it seems that relevant to my fixing patch.
commit 9546eb92cb648a8bba0aa9d5930ac751e6e5b9a4

mmc: fix the wrong disabling clock
When power is off, clock is not disabling.
Because it's passed to 1, mmc->clock should be set to f_min value.
Some drivers can't initialize the eMMC/SD card with current status.
This patch is to fix the disabling clock value to 0.
Fixes: 2e7410d76ad1 ("mmc: disable the mmc clock during power off")
