34 stage. If the kernel fails to uncompress, then the watchdog
35 will trigger a reset and the system should restart.

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

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