Not that I'm against dual SD slots, but from what I see, NAND and eMMC
share the same pins so it should be easy enough to add the bga
footprint and the required passives.

The MarsBoard A20 has pads for both NAND and eMMC in the same
footprint so you can use one or the other without losing board space.
