[PATCH 0/5] hw/cpu/cluster: Restrict CPU cluster to a particular CPU type

[Philippe Mathieu-Daudé]

Following Alex's comment [1] on "Introduce hybrid CPU topology"
RFC [2], this series strengthen a bit the CPU cluster by
restricting it to a particular CPU type.

We'd rather have a single way of creating heterogeneous (hybrid)
CPU topology. Note the CPU cluster is not user-creatable, so few
more work is required in this area.

Based-on: <20230216122524.67212-1-philmd@linaro.org>
