/**

The entry point of PE/COFF Image for a Standalone MM Driver.

|
|
|
This function is the entry point for a Standalone MM Driver.
|
|
This function must call ProcessLibraryConstructorList() and

ProcessModuleEntryPointList().
|
|
If the return status from ProcessModuleEntryPointList()
|
|
is an error status, then ProcessLibraryDestructorList() must be called.
|
|
The return value from ProcessModuleEntryPointList() is returned.
|
|
If _gMmRevision is not zero and SystemTable->Hdr.Revision is
|
|
less than _gMmRevision, then return EFI_INCOMPATIBLE_VERSION.
|
|
|
|
@param ImageHandle The image handle of the Standalone MM Driver.
|
|
@param MmSystemTable A pointer to the MM System Table.
|
|
|
|
@retval EFI_SUCCESS The Standalone MM Driver exited normally.
|
|
@retval EFI_INCOMPATIBLE_VERSION _gMmRevision is greater than
|
|
MmSystemTable->Hdr.Revision.
