/* 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
