/* The MPS2 and MPS2+ dev boards are FPGA based (the 2+ has a bigger
* FPGA but is otherwise the same as the 2). Since the CPU itself
* and most of the devices are in the FPGA, the details of the board
* as seen by the guest depend significantly on the FPGA image.
* This source file covers the following FPGA images, for TrustZone cores:
* "mps2-an505" -- Cortex-M33 as documented in ARM Application Note AN505
* "mps2-an521" -- Dual Cortex-M33 as documented in Application Note AN521
*
* Links to the TRM for the board itself and to the various Application
* Notes which document the FPGA images can be found here:
* https://developer.arm.com/products/system-design/development-boards/fpga-prototyping-boards/mps2

* Application Note AN521:

* The AN505 defers to the Cortex-M33 processor ARMv8M IoT Kit FVP User Guide
* (ARM ECM0601256) for the details of some of the device layout:
* http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ecm0601256/index.html
* Similarly, the AN521 uses the SSE-200, and the SSE-200 TRM defines
* most of the device layout:
