The SSE-200 hardware has configurable integration settings which determine whether its two CPUs have the FPU and DSP: * CPU0_FPU (default 0) * CPU0_DSP (default 0) * CPU1_FPU (default 1) * CPU1_DSP (default 1) Similarly, the IoTKit has settings for its single CPU: * CPU0_FPU (default 1) * CPU0_DSP (default 1) Of our four boards that use either the IoTKit or the SSE-200: * mps2-an505, mps2-an521 and musca-a use the default settings * musca-b1 enables FPU and DSP on both CPUs Currently QEMU models all these boards using CPUs with both FPU and DSP enabled. This means that we are incorrect for mps2-an521 and musca-a, which should not have FPU or DSP on CPU0. Create QOM properties on the ARMSSE devices corresponding to the default h/w integration settings, and make the Musca-B1 board enable FPU and DSP on both CPUs. This fixes the mps2-an521 and musca-a behaviour, and leaves the musca-b1 and mps2-an505 behaviour unchanged.
