- depends on PLAT_S3C && PM && CRC32
- help
- 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.

- help
- 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 wil identify any
- faults with better precision.

- must have been initialised by the boot-loader before use.
