So in general we don't have those kind of command enables in the defconfig. It might be worth discussing whether we should enable the really useful "ums" command by default, for all Allwinner devices enabling USB gadget mode, but this would be done differently.
CONFIG_SCSI_AHCI=y +# CONFIG_USB_FUNCTION_FASTBOOT is not set
Why is this explicitly disabled? From what I can see, it doesn't hurt to leave it enabled (through Kconfig's default), it does not interfere with other gadgets like UMS or Ethernet.

This last symbol is enabled automatically by the FASTBOOT option.
