          Say y to enable the watchdog during the kernel decompression
          stage. If the kernel fails to uncompress, then the watchdog
          will trigger a reset and the system should restart.

          Say y here to use the watchdog to reset the system if the
          kernel decompressor detects an error during decompression.

        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.

          this configuration should be between zero and two. The port
          must have been initialised by the boot-loader before use.
