This patch series provides a composite gadget for downloading code to u-boot targets.
The Linux's composite gadget framework is used. For this series a special function (f_usbd_thor) has been added. It supports a THOR protocol for sending data.
Other functions and protocols backends can be easily added - for instance supporting DFU.
