Hm, unfortunately there is no such document, as far as I know.

The Ethernut Wiki has a lot of samples, but mostly from the users point
of view:

A good starting point for your driver might be the SD Driver
implementation for LPC17xx:

nut/arch/cm3/dev/nxp/lpc177x_8x_mmcard_sdio.c

If you have any special question or need support, just let me know.
