Add module that initializes a CPU for the SMM environment and installs the first level SMI handler. This module along with the SMM IPL and SMM Core provide the services required for DXE_SMM_DRIVERS to register hardware and software SMI handlers. CPU specific features are abstracted through the SmmCpuFeaturesLib Platform specific features are abstracted through the SmmCpuPlatformHookLib Several PCDs are added to enable/disable features and configure settings for the PiSmmCpuDxeSmm module [jeff.fan@intel.com: Fix code style issues reported by ECC] Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Michael Kinney <michael.d.kinney@intel.com> Reviewed-by: Jeff Fan <jeff.fan@intel.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@18646 6f19259b-4bc3-4df7-8a09-765794883524
