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

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

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