Do you need CMD_USB_MASS_STORAGE for your tests ? Enabling
CMD_USB_MASS_STORAGE really seems orthogonal to enabling GADGET
mode to me, esp. since it is only useful in host mode AFAICT.

Chen-Yu did something similar in a patch enabling host mode for a
different sunxi board and here is what I replied:

"
If we want to enable CONFIG_CMD_USB_MASS_STORAGE on sunxi, we really
should do so on all boards (feel free to submit a patch for this).

e.g. add something like this to board/sunxi/Kconfig:

config CMD_USB_MASS_STORAGE
     default y

So that we can still disable it in case there are space constraints,
but normally we enable it on all sunxi boards offering a
consistent set of available commands.
"

The same goes for this patch, otherwise this patch is:

Ig you want to feel free to apply this directly
(given that I've send out a sunxi pull-req recently).

Hans
