MIPS virt board is design to utilize existing VirtIO infrastures
but also comptitable with MIPS's existing internal simulation tools.
It includes virtio-pci, virtio-mmio, pcie gpex, flash rom, fw_cfg,
goldfish-rtc and MIPS CPS system.
It should be able to cooperate with any MIPS CPU cores.

qemu-system-mips64el: Property 'mips-cps.num-core' not found
I'm worried. I suppose you want this property:
DEFINE_PROP_UINT32("num-vp", MIPSCPSState, num_vp, 1),
Is your series based on mainstream QEMU?
