Native coreboot MP Init. 2. FSP to do MP Init. 3. FSP to make use of coreboot MP service PPI to perform MP Initialization Change-Id: Ifbea463fdaf97d68c21a759c37f49492d58a056b Signed-off-by: Subrata Banik Reviewed-on: https://review.coreboot.org/c/coreboot/+/30287 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi --- src/soc/intel/common/block/cpu/Kconfig | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) diff --git a/src/soc/intel/common/block/cpu/Kconfig b/src/soc/intel/common/block/cpu/Kconfig index 48f3f1645c..9ec5307e48 100644 --- a/src/soc/intel/common/block/cpu/Kconfig +++ b/src/soc/intel/common/block/cpu/Kconfig @@ -50,3 +50,30 @@ config INTEL_CAR_NEM_ENHANCED the modified data will be lost and NEM results will be inconsistent.
