This patch fixes the MPC8548 CDS rebooting procedure.

Dai, I'm avoid taking patches for 85xx that effect new=20
functionality.  If you want change this to work with=20
arch/powerpc and make it a run time check for 8548.

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?=20
And how do you want me to do run time check? Check SVR?=20
