All required APIs to create MP service structure. 2. Function to get MP service PPI status MP specification here: http://github.com/tianocore/edk2/blob/master/MdePkg/Include/Ppi/MpServices.h coreboot design document here: ../Documentation/soc/intel/icelake/MultiProcessorInit.md Supported platform will call fill mp_services structure so that FSP can install the required PPI based on coreboot published structure. BRANCH=none BUG=b:74436746 TEST=Able to publish MP service PPI in coreboot.
