The entry point of PE/COFF Image for a DXE Driver, DXE Runtime Driver, DXE SMM Driver, or UEFI Driver.
This function is the entry point for a DXE Driver, DXE Runtime Driver, DXE SMM Driver,
or UEFI 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 _gDriverUnloadImageCount is greater
than zero, then an unload handler must be registered for this image and the unload handler
must invoke ProcessModuleUnloadList().
If _gUefiDriverRevision is not zero and SystemTable->Hdr.Revision is less than _gUefiDriverRevison,
then return EFI_INCOMPATIBLE_VERSION.
@param ImageHandle The image handle of the DXE Driver, DXE Runtime Driver, DXE SMM Driver, or UEFI Driver.
@param SystemTable A pointer to the EFI System Table.
@retval EFI_SUCCESS The DXE Driver, DXE Runtime Driver, DXE SMM Driver,
