[PATCH 8/8] qi-add-sc36410-mci.patch
Andy Green

Tue Oct 21 12:42:41 CEST 2008
This heavily adapts the Samsung U-Boot hs_mmc code and combines it with the
SD / SDHC startup code written for glamo-mci stuff that is known to work OK
with common SD and SDHC.
tla01 is changed to use the implementation.
