Re: [RFC PATCH] power-management elements for 603e/fsl

As some of you would know, it is not a real suspend-to-RAM, since kurobox' 
hardware doesn't support powering down CPU and peripherals while keeping 
RAM in self-refresh. So, this patch just sends the SoC and the CPU to 
SLEEP. It also needs some extra patches for timer suspend / resume, so, 

The early powerbooks also put the CPU into sleep mode, rather than
powering it off, so I think you can say that what you are doing is
suspend to RAM, as long as it manages to reduce power consumption
substantially, and you have a way to wake it up (e.g. via a keypress
or a LAN packet).

this alone will not work properly. Besides, I am not where to put and how 
to call these functions. So far I put them in fsl namespace as that'll, 
probably, be similar among Freescale chips? Maybe it's better to call this 
mode standby, not str?

What you have done looks OK to me.  If we need to move things around
later, that can be done easily enough.
