3) SD bus support. I know that I can use SD card in SPI mode but on some

This is MMC/SD disk driver for Freescale Kinetis and iMX.
https://sourceforge.net/projects/ecosfreescale/files/devs/SDHC/
Upper layer (based on SPI MMC driver) and HW dependent (Freescale) parts
are placed in separate packages.
Jerzy, can you see if STM support can be added?
Note: The aim of this project is support for MMC/SD memory cards (I.E.
disk drive) SDIO is out of scope.
Comments are welcome.
