	  Enable the PM code's memory area checksum over sleep. This option
	  will generate CRCs of all blocks of memory, and store them before
	  going to sleep. The blocks are then checked on resume for any
	  errors.

	  Note, this can take several seconds depending on memory size
	  and CPU speed.

	  Set the chunksize in Kilobytes of the CRC for checking memory
	  corruption over suspend and resume. A smaller value will mean that
	  the CRC data block will take more memory, but will identify any
	  faults with better precision.
