Yes that's right since yesterday's merge of MMC into u-boot-arm (prior to that there was no working MMC!). Let's hold off applying this patch until you are done.
I have to disagree with the 'no working MMC' statement. When I submitted my Tegra2 MMC driver in May, it was working fine on Seaboard (hadn't tested yet on Harmony since mine was dead). At that time, DCACHE was off, so no concurrency issues nor hangs were seen. Wolfgang merged it w/master in mid-July.
Just correcting for the record,
Yes I suspect you are right, it could just be my Seaboard - I have a different one from what I was using a few months ago. With this new one I see:
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.
