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.
