[edk2-devel] [PATCH 0/2] Align the PPTT tables with qemu configuration

["Xiong Yining" <xiongyining1480@phytium.com.cn>]

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
