Hi all,
                 I have got u-boot-1.1.4 on MPC8540 board.I'm supposed 
to put the processor in nap mode for power mangement.I have enabled the 
doze mode bit initially in the power mangement register which is in 
u-boot-1.1.4/include/asm-ppc/immap_85xx.h,but i couldnt find any change 
during the execution.i have disabled the unused interfaces to reduce the 
power,is there any code for doing putting processor in nap mode and 
doing power mangement? can any one help me out of this.

Thanks in advance
