[U-Boot] [u-boot PATCH v2 00/40] dra7xx: am43xx: add dwc3 gadget driver support and enable dfu

[Kishon Vijay Abraham I]

This patch series ports dwc3 gadget driver from linux kernel (3.19-rc1)
to u-boot.

Changes from v2:
*) Made all the buffers which should be flushed to be memaligned and made
   flush_dcache_range to flush only those memory regions.
*) In dwc3_ep0_complete_data, changed the conditional check in implementing
   chained TRB for ep0.
*) Other misc fixes from review comments for v1.
*) Added "Reviewed-by: Lukasz Majewski <l.majewski at samsung.com>" in all the
   patches.

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.
