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.
Regards, Gérald

Remove udelay, because card status is polled in a loop.
