image, like the existing mps2-an521. It has a usefully larger amount
of RAM, and a PL031 RTC, as well as some more minor differences.
In real hardware this image runs on a newer generation of the FPGA
board, the MPS3 rather than the older MPS2. Architecturally the two
boards are similar, so we implement the MPS3 boards in the mps2-tz.c
