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

72 depends on PLAT_S3C && PM && CRC32
73 help
74 Enable the PM code's memory area checksum over sleep. This option
75 will generate CRCs of all blocks of memory, and store them before
76 going to sleep. The blocks are then checked on resume for any
77 errors.
78
79 Note, this can take several seconds depending on memory size
80 and CPU speed.

87 default 64
88 help
89 Set the chunksize in Kilobytes of the CRC for checking memory
90 corruption over suspend and resume. A smaller value will mean that
91 the CRC data block will take more memory, but wil identify any
92 faults with better precision.

102 such as the `Uncompressing...` at start time. The value of
103 this configuration should be between zero and two. The port
104 must have been initialised by the boot-loader before use.
