In my case, I hadn't found much information about accessing SDcards in anything other than SPI mode, but I guess if it turns out it is basically just QSPI and the same byte-oriented protocol as before, that would be useful to know.
 
The SD card specification covers both in detail.
But the 4 bit wide SD access will depend a lot on what hardware support you have. I used an ARM (in a Teensy 3.2) to do the job. Mostly quite similar to SPI access.
