To align the CPU topology information recognized by the operating system with the CPU topology information configured by QEMU, we need to get the information of topology to have complex PPTT tables setups.
When creating the pptt table, we considered the cluster layer, SBSA Reference Platform has cluster support on qemu https://lists.gnu.org/archive/html/qemu-devel/2024-03/msg02951.html. We use the SMC to get CPU topology information, the TF-A part is here https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/27189.
