I guess this is the basis of some of the disagreement, I have exactly
one device with SD card here -- and I have a lot of other devices -- and
that is an old AT32 evaluation board.

Reading the datasheet, as far as I can make out there are three equal
MMC / SD / SDIO peripherals on the CPU, so if the physical form factor
allowed it, it should offer SDIO. (But the datasheet doesn't come out
and say that directly curiously enough).
