/* 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.
 * We model the following FPGA images:
 *  "mps2-an385" -- Cortex-M3 as documented in ARM Application Note AN385
 *  "mps2-an511" -- Cortex-M3 'DesignStart' as documented in AN511
 *
 * Links to the TRM for the board itself and to the various Application
 * Notes which document the FPGA images can be found here:

	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-an511" -- Cortex-M3 'DesignStart' as documented in AN511
