In current implementation we are allocating boardobj in nvgpu_boardobj_construct_super for all units and assigning that pointer to boardobj type, as the size differe for different units assigning the boardobj pointer to a common type will give violations. Fixing them by allocating mem a head and later call construct_super for elements initialization.
