This patch does not impact functionality. It aims to clarify the synchronization flow between the BSP and APs to enhance code readability and understanding: Steps tianocore#6 and tianocore#11 are the basic synchronization requirements for all cases. Steps #1 is additional requirements if the MmCpuSyncModeTradition mode is selected. Steps #1, #2, #3, tianocore#4, tianocore#5, tianocore#7, tianocore#8, tianocore#9, and tianocore#10 are additional requirements if the system needs to configure the MTRR. Steps tianocore#9 and tianocore#10 are additional requirements if the system needs to support the mSmmDebugAgentSupport. Signed-off-by: Jiaxin Wu <[email protected]>
