Subsystems such as USB expect dma_map_single() and dma_unmap_single() to do dcache flush/invalidate operations as required. For example, see drivers/usb/gadget/udc/udc-core.c::usb_gadget_map_request(). Currently drivers do this locally, (see drivers/usb/dwc3/ep0.c, drivers/mtd/nand/raw/denali.c etc..) Update arch specific dma_map_single() and dma_unmap_single() APIs to do cache flush/invalidate operations, so that drivers need not implement them locally.

This throws warnings on am335x_evm, please re-check and resubmit, thanks.
This is caused by recently merged changes in U-Boot tree. I have posted v2 with this issue fixed. Thanks!
