  13 * This is a model of the "system control element" which is part of the
  14 * Arm IoTKit and documented in
  15 * http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ecm0601256/index.html
  16 * Specifically, it implements the "system information block" and
  17 * "system control register" blocks.

  20 *  + sysbus MMIO region 0: the system information register bank
