Suspend/Resume support for PPC

Hi all,

I am working on powerpc mpc5200 with QNX.
i am trying to implement the suspend/resume of the ppc…i hav been able to suspend the cpu
by putting it into deep sleep mode.
but i am not able to resume it properly.if i try to resume it it boots up with the normal boot sequence.if anyone have implemented the same please help me.
presently my plan is to save the wakeup routine address in ram location 0.and put the cpu to deep sleep mode,put the SDRAM in to self refresh mode.

thanks in advace…
