I think the issue is that MMC/SD work OK with Tom's patch "tegra2: Enable
MMC for Seaboard", which isn't yet merged into mainline U-Boot. Without
that, neither the MMC nor SD slot worked for me.

For Harmony you'll need my patch "tegra2: Move board_mmc_init into board
files", which is part of a series that's not yet merged.
