Patch 1/2 is the start of addressing the issue that the Aff0 field of the MPIDR is no longer guaranteed to be the core, and should be referred to in a more generic way: for example it could be the thread, with Aff1 being the core and Aff2 the cluster. Clearly much more work is needed to fully remove that assumption.
Patch 2/2 implements the EFI_MP_SERVICES_PROTOCOL for DXE in Library/MpInitLib. CpuDxe initializes the MP support, and as a result gains a dependency on MpInitLib. ArmVirt.dsc.inc needs updated to add the new library, as will all AARCH64 platforms. Cores are powered on and turned off using PSCI. Note that minimal CPU setup is done: for example the MMU and caches are left disabled.
