Support for designware USB device controller (UDC) exists in the u-boot for SPEAr platform. This patchset makes the driver more generic so that it can be used across multiple platforms.
V2: - Configure the gadget in HS only if CONFIG_USBD_HS is defined - Made local functions static in a separate commit - In "Fix memory nonalignment issue" used memcpy instead of copying byte-by-byte - Define the HS_PACKET_SIZE unconditionally
V1: - Added support for designware UDC in a more generic way
