I can't say. I don't have access to this site. Does your EVM have an SD Card connector on MMC2? If it does you will only need to reconfigure Linux. If there is a WiFi module physically attached to MMC2 you will need to make hardware modifications to your board.

I don't have the EVM schematics, but from what I read on the Internet I'm not sure if this can be done. There seems to be a level shifter on this interface, however I cannot say for sure, not having the schematics to look at.

I found this forum post that is related to your question: http://e2e.ti.com/support/embedded/linux/f/354/t/60427.aspx?pi196120=2. Perhaps if you ask on this thread you will get what you need to make MMC2 work.
