The FSP apparently can service a FETCH_SP_DATA after HV functional --
end of OPL. We can stick the preload in there... but... the FSP folks
aren't sure about the earliest time we can get a OCC load; I will write
to the OCC folks to get that info.

End of OPL is significantly early wrt loading other lids... so we will
not hit the concurrency seen now.
