| /* 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 |
| * "mps2-an524" -- Dual Cortex-M33 as documented in Application Note AN524 |
| * "mps2-an547" -- Single Cortex-M55 as documented in Application Note AN547 |
| * |
| * Links to the TRM for the board itself and to the various Application |
| * Notes which document the FPGA images can be found here: |

| * 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: |
| * https://developer.arm.com/documentation/ecm0601256/latest |
| * Similarly, the AN521 and AN524 use the SSE-200, and the SSE-200 TRM defines |
| * most of the device layout: |
| * https://developer.arm.com/documentation/101104/latest/ |
| * and the AN547 uses the SSE-300, whose layout is in the SSE-300 TRM: |
