Somebody in the thread at some point said:
| Isn't SDIO related to the software (eg driver) only?
|
| SD and SDIO are basically the same SPI or 4-databits-SPI-like hardware
| protocol with additional commands, I guess (at least, this is what i saw
| on the freely available spec available at sdcard.org <http://sdcard.org>)

I believe there is some kind of additional interrupt support needed.
