The following configurations were tested and all booted TDs successfully:
(1) gmem_in_place_conversion=1, in-place conversions + in-place-add init mem
(2) gmem_in_place_conversion=1, in-place conversions + out-of-place-add init mem
(3) gmem_in_place_conversion=0, out-of-place conversions + out-of-place-add init mem
