[U-Boot] exynos: snow: external SD/MMC broken

Hi,

while trying latest u-boot GIT on snow (Google Chromebook ARM), I encountered some problems with external SD card. I cannot access to external SD card ('mmc dev 1' just returns 'Card did not respond to voltage select!' and then 'Timeout') whereas I have access to internal eMMC (with 'mmc dev 0').

Any idea what could be the problem?

On arndale board (same SoC), there is no such SD/MMC problem.
