How to enable Master Access of SWT in MPC5748G?

Master access of SWT is disabled in  Startup.S as follows.

e_lis      r3, 0x7F00       // -> 0xFF00, master access enable
e_or2i    r3, 0x010A

So I have to modify Startup.S file if I want to access SWT control register. Obviously, this is not a good idea.

But, how to enable Master Access of SWT in MPC5748G apart from that way?
