13 * This is a model of the "system control element" which is part of the
14 * Arm IoTKit and documented in
15 * https://developer.arm.com/documentation/ecm0601256/latest
16 * Specifically, it implements the "system information block" and
17 * "system control register" blocks.
18 *
19 * QEMU interface:
20 * + QOM property "sse-version": indicates which SSE version this is part of
21 * (used to identify whether to provide SSE-200-only registers, etc)
22 * + sysbus MMIO region 0: the system information register bank
23 * + sysbus MMIO region 1: the system control register bank
