From 6662cb3dc2c4fe56cb75f83e1e7015287870cf01 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Thu, 12 Apr 2018 19:25:37 +0530 Subject: drivers/intel/fsp2_0: Implement EFI_MP_SERVICES_PPI structure APIs This patch ensures to have below listed features: 1. 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.
