* This is a model of the "system control element" which is part of the

* Arm IoTKit and documented in
|
|
* http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ecm0601256/index.html

* Specifically, it implements the "system information block" and
|
|
* "system control register" blocks.

|
|
* QEMU interface:
|
|
* + QOM property "SYS_VERSION": value of the SYS_VERSION register of the
|
|
* system information block of the SSE
|
|
* (used to identify whether to provide SSE-200-only registers)
|
|
* + sysbus MMIO region 0: the system information register bank
|
|
* + sysbus MMIO region 1: the system control register bank
