Hi Kumar, what kind of new feature is affected by this bug fix? 8548
requires reboot to set the hardware reset bits. The mpc85xx_restart() is
not ported to arch/powerpc yet. Which portion of the arch/powerpc code
should be modified in order to restart the machine correctly? 
And how do you want me to do run time check? Check SVR?
