This patch series ports dwc3 gadget driver from linux kernel (3.19-rc1) to u-boot.
Changes from RFC: *) A patch has been added to copy the driver from linux kernel to u-boot and then it's modfied to make it work in u-boot. This will help to understand the changes that's been done to make it work in u-boot and will also be easier to review. *) Implemented chained TRB support in dwc3 ep0 so that we need not increase the size of bounce buffer
Testing: *) tested DFU RAM and DFU MMC in dra7xx and am43xx
TODO: *) Add Kconfig support *) Adapt dwc3 driver to use the driver model. *) Make composite driver similar to the one in linux kernel.
