Bootloader MCF51JM

I have a boot loader and an application in the MCF51 series.   Every example I see from freescale launches a  boot loader upon reset while the user is pressing a button or pin.  We dont get input from the user that way.  We want to launch the boot loader from our application.   Is there a very simple way to do this ?   We have read a lot of questions about calling a function at a fixed address but see no answers as to how to do this.  We want an extremely simple way to do this.  A byte in RAM that doesn't get rest when the process resets would be great but calling a boot loader function from our application if its in a fixed location might work to.  Any other ideas or anyone know how to do these ?
