Hi Tom,
Introduce a hidden USB_FUNCTION_DFU Kconfig option and select it for CMD_DFU (as we must have the DFU command enabled to do anything DFU). Make all of the entries in drivers/dfu/Kconfig depend on CMD_DFU and add options for all of the back end choices that DFU can make use of.

Once ack'd I'll run moveconfig.py to migrate everyone over and check for size changes. This will also depend on the patch I sent to change the malloc pool size on TI parts as we otherwise will now expose the bug about DFU_MMC being unset.
