Hi John,

Did you apply this patch?

After applying the patchset, mmc init fails with following message.

...

...

Controller never released inhibit bit(s).

I have uploaded the test branches on [1] for you to have a look. [1] git://git.linaro.org/landing-teams/working/samsung/u-boot.git (test/test/u-boot-v2012.07 test/test/u-boot-v2012.07-mmcfix)

Jaehoon,

I get timeouts on multiblock mmc reads with v2012.07 u-boot. I did a bisect and found that it is broken back to

442d55685e1e2310d546044a6519ae73e4ba348a mmc: support the sdhci instead of s5p_mmc for samsung-soc and 236bfecff8091356d81e79da3281b9e4af967468 mmc: add the quirk to use the sdhci for samsung-soc

That second commit seems to adds two new quirks SDHCI_QUIRK_NO_HISPD_BIT and SDHCI_QUIRK_BROKEN_VOLTAGE but I don't see any board using these so perhaps these need to be enabled for origen?

Thanks, --john
