Currently a machine can have multiple CPUs as long as
they are from the same guest architecture. So you can
have both Arm M-profile and A-profile CPUs (including
mixing 32-bit only and 64-bit CPUs). But you can't
have combinations like an Arm CPU and a PPC CPU.

I think the only mixed-CPU-type board we have in
QEMU at the moment is one of the Xilinx boards which
has both Cortex-R5 and Cortex-A53 CPUs.
