Starting point: Suspend to RAM on embedded devices?

[Wappler Marcel]

Hi all,

I am looking for ways to let an ARM9 based embedded device running Linux go to a "suspend to RAM" like mode. In my opinion this
could enable a HIFI equipement like "power-off" and "power-on" feeling with quick response (less than 2 seconds) and much less power
consumption in the standby mode than during normal operation.

- Is there public available documentation about APM like features on ARM architectures?
- Is there a mainstream Linux platform (best if also ARM9 based) which has achieved this already?
- I am also interested in experiences with applications running on such platforms, 
  trigger like systems which inform the apps and so on...

Thank you Marcel
