     13 * This is a model of the Serial Communication Controller (SCC)
     14 * block found in most MPS FPGA images.
     15 *
     16 * QEMU interface:
     17 *  + sysbus MMIO region 0: the register bank
     18 *  + QOM property "scc-cfg4": value of the read-only CFG4 register
     19 *  + QOM property "scc-aid": value of the read-only SCC_AID register
     20 *  + QOM property "scc-id": value of the read-only SCC_ID register
     21 *  + QOM property "scc-cfg0": reset value of the CFG0 register
     22 *  + QOM property array "oscclk": reset values of the OSCCLK registers
     23 *    (which are accessed via the SYS_CFG channel provided by this device)
     24 *  + named GPIO output "remap": this tracks the value of CFG0 register
     25 *    bit 0. Boards where this bit controls memory remapping should
     26 *    connect this GPIO line to a function performing that mapping.
     27 *    Boards where bit 0 has no special function should leave the GPIO
     28 *    output disconnected.
