Guillaume,

I 'think' I got the peripheral mode working on my DM3730. Like
before, it only supports host or gadget, and I set the patch up to
look at whether or not CONFIG_USB_MUSB_GADGET is set.

I was able to get Fastboot devices to appear and an sdp device to
appear. I wasn't setup to actually run data through those interfaces,
but my host machine recognized them.

Feel free to try the patches and please give feedback. They are
located: https://patchwork.ozlabs.org/project/uboot/list/?series=82418
