The MM communicate 2 protocol was introduced to factor out the mismatch
between traditional MM, which requires the physical address of the MM
buffer to be passed, and standalone MM, which copies the MM communicate
buffer data into a separate buffer, requiring the virtual address. For
this reason, MM communicate 2 carries both addresses, allowing the
implementation to decide which address it needs.
This hides this implementation detail from the callers of the protocol,
which simply passes both addresses without having to reason about what the
implementation of the protocol actually needs.
Note that the old version of the protocol is retained, in order to support
existing implementations that don't require this flexibility.

According to PI specification, EndOfDxe Event should be signaled before
DxeSmmReadyToLock protocol installation. This update is ASSERT if EndOfDxe
Event is not signaled when DxeSmmReadyToLock protocol installed. And do
REPORT_STATUS_CODE() also.

And also SMM Ready To Boot.
The SMM Exit Boot Service protocol is to be published by the SMM
Foundation code to associate with EFI_EVENT_GROUP_EXIT_BOOT_SERVICES
to notify SMM driver that system enter exit boot services.
The SMM Legacy Boot protocol is to be published by the SMM
Foundation code to associate with EFI_EVENT_LEGACY_BOOT_GUID
to notify SMM driver that system enter legacy boot.
The SMM Ready To Boot protocol is to be published by the SMM
Foundation code to associate with EFI_EVENT_GROUP_READY_TO_BOOT
to notify SMM driver that system enter ready to boot.
After them, any SMM drivers can get protocol notify on what happened
in DXE phase, then there is no need to let each individual SMM driver
to register SMM Communication Handler for that.
