Hi Mario, I test this patch but it is unsuccessfull with the seevaplug :
After upgrade with U-Boot 2015.01-rc2-dirty (Nov 25 2014 - 08:10:39) Marvell-Sheevaplug Marvell>> mmc list MVEBU_MMC: 0 Marvell>> mmc part Marvell>> mmc dev 0 1 Card did not respond to voltage select! Marvell>> mmc rescan Marvell>> ext2ls mmc 0:1 ** Bad device mmc 0 ** Marvell>> The same master branch (without your patch) work as before... The udelay removal get the MVEBU_MMC driver bug with sheevaplug.
