[ARM] 4509/1: S3C: Create initial arch/arm/plat-s3c
Create the initial arch/arm/plat-s3c directory and start
linking it into the arch/arm build heirarchy ready to
receive the generic parts of the S3C24XX support to be
used when adding S3C6400 devices.

+ bool "S3C2410 PM Suspend Memory CRC"
+ 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.

+ depends on PLAT_S3C && PM && S3C2410_PM_CHECK
+ default 64
+ 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.
