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