I doubt that dfu_nand.c is the right place for this.  What if I start
using DFU on NOR flash?  The decisions which device type (NAND, MMC,
NOR, USB mass storage, ...) to habdle on one side, and which partition
type / image type (raw, UBI volume, file, ...) on the other side are
fully orthogonal to each other.  They should be handled by independent
code, and not one of them repeated for all implementations of the
other.

Best regards,

Wolfgang Denk
