powerpc/85xx: add sleep and deep sleep support
In sleep PM mode, the clocks of e500 core and unused IP blocks is
turned off. IP blocks which are allowed to wake up the processor
are still running.
Some Freescale chips like MPC8536 and P1022 has deep sleep PM mode
in addtion to the sleep PM mode.
While in deep sleep PM mode, additionally, the power supply is
removed from e500 core and most IP blocks. Only the blocks needed
to wake up the chip out of deep sleep are ON.
This patch supports 32-bit and 36-bit address space.
The sleep mode is equal to the Standby state in Linux. The deep sleep
mode is equal to the Suspend-to-RAM state of Linux Power Management.
Command to enter sleep mode.
echo standby > /sys/power/state
Command to enter deep sleep mode.
echo mem > /sys/power/state
