The IO interface for SDMC/NAND seems to be very similar to the DSi; see libnds for [https://github.com/devkitPro/libnds/blob/master/source/arm7/sdmmc.c sample code] and [https://github.com/devkitPro/libnds/blob/master/include/nds/arm7/sdmmc.h documentation].

3DS SDMC/NAND IO registers are located at 0x10006000 and apparently mirrored at 0x10007000. It seems the 0x10007000 mirror is never used on retail units.
