Just saw this issue on a mx6ul pico board: after adding I2C support then the eMMC could not longer be written:
=> saveenv Saving Environment to MMC... Writing to MMC(0)... The SD card is locked. Can not write to a locked card.
mmc write failed failed
Your patch allows me to write to the eMMC succesfully:

Looks like this is an issue with the MX6UL IOMUXC, not the esdhc driver itself, so maybe we should not do this change for all other SoCs.
If I manually do: => mw.l 20E066C 2 Then 'saveenv' works fine.
Shouldn't we fix this in the MX6UL IOMUXC code instead?
