[PATCH] ARM: 2764/1: S3C24XX - Common PM functions for Simtec boards
Patch from Ben Dooks
All current S3C24XX implementations from Simtec share the same
requirements for suspend/resume information.
This patch moves the save code out of the mach-bast.c file,
and into it's own so it can be shared by all the current
Simtec S3C24XX implementations.
