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.

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,
