[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.

+config S3C2410_BOOT_WATCHDOG
+ bool "S3C2410 Initialisation watchdog"
+ depends on PLAT_S3C && S3C2410_WATCHDOG
+ help
+ 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.
+
+config S3C2410_BOOT_ERROR_RESET
+ bool "S3C2410 Reboot on decompression error"
+ depends on PLAT_S3C
+ help
+ Say y here to use the watchdog to reset the system if the

+config S3C2410_PM_DEBUG
+ bool "S3C2410 PM Suspend debug"
+ depends on PLAT_S3C && PM
+ help
+ Say Y here if you want verbose debugging from the PM Suspend and
+ Resume code. See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>
+ for more information.
+
+config S3C2410_PM_CHECK
+ 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.
+
+ See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>

+config S3C2410_PM_CHECK_CHUNKSIZE
+ int "S3C2410 PM Suspend CRC Chunksize (KiB)"
+ 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.

+config S3C2410_LOWLEVEL_UART_PORT
+ int "S3C2410 UART to use for low-level messages"
+ depends on PLAT_S3C
+ default 0
+ help
+ Choice of which UART port to use for the low-level messages,
+ such as the `Uncompressing...` at start time. The value of
+ this configuration should be between zero and two. The port
+ must have been initialised by the boot-loader before use.
