I remember that we discussed this before, but now that I think  about
this  again  I changed my mind: I don't think there is a valid reason
to add this code.

No. You write: i.MX hangs when doing "reset". I guess the board  does
not  hand  if  you  power cycle it, or if you press the reset button,
right? So the conclusion is that the reset code does not do what  you
think it does - i. e. it does not cause a reset of the processor.

This is a problem that should be fixed. Once fixed, this patch is not
needed any more.

Best regards,
