              if (STRICT_ALIGNMENT)
                warning (OPT_Wpacked, "packed attribute causes inefficient "
                         "alignment for %qE", name);
              else
                warning (OPT_Wpacked,
                         "packed attribute is unnecessary for %qE", name);


The warning is happening because arm is a strict alignment target that means
the target will not do a hardware unaligned load and will require load byte by
byte.
