It is still not a good idea.

Considered that data ruin is a very serious problem, you need to find
the root cause, then you may enable autocmd12.

Also you didn't answer my question, will omap3/4 mmc controller
just support SD card only?  The TRM said it clearly that the feature
is only supported for SD card.
