      2 * QEMU model of the USB DWC3 host controller emulation.
      3 *
      4 * This model defines global register space of DWC3 controller. Global
      5 * registers control the AXI/AHB interfaces properties, external FIFO support
      6 * and event count support. All of which are unimplemented at present. We are
      7 * only supporting core reset and read of ID register.
