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  * We model the following FPGA images:
17  *  "mps2-an385" -- Cortex-M3 as documented in ARM Application Note AN385
18  *  "mps2-an386" -- Cortex-M4 as documented in ARM Application Note AN386
19  *  "mps2-an500" -- Cortex-M7 as documented in ARM Application Note AN500
20  *  "mps2-an511" -- Cortex-M3 'DesignStart' as documented in AN511
21  *
22  * Links to the TRM for the board itself and to the various Application
23  * Notes which document the FPGA images can be found here:
