12 /* The MPS2 and MPS2+ dev boards are FPGA based (the 2+ has a bigger
13  * FPGA but is otherwise the same as the 2). Since the CPU itself
14  * and most of the devices are in the FPGA, the details of the board
15  * as seen by the guest depend significantly on the FPGA image.
16  * This source file covers the following FPGA images, for TrustZone cores:
17  *  "mps2-an505" -- Cortex-M33 as documented in ARM Application Note AN505
18  *  "mps2-an521" -- Dual Cortex-M33 as documented in Application Note AN521
19  *
20  * Links to the TRM for the board itself and to the various Application
21  * Notes which document the FPGA images can be found here:

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