Kukjin Kim b130d5c295 ARM: S3C24XX: change the ARCH_S3C2410 to ARCH_S3C24XX
This patch changes the ARCH name to "ARCH_S3C24XX" for Samsung
S3C2410, S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443,
and S3C2450 SoCs so that we can merge the mach-xxx directories
and plat-s3c24xx dir. to just one mach-s3c24xx for them.

I think this should be sent to upstream via samsung tree because
this touches many samsung stuff.

config SAMSUNG_PM_DEBUG

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 S3C_PM_DEBUG_LED_SMDK
bool "SMDK LED suspend/resume debugging"
depends on PM && (MACH_SMDK6410)

Say Y here to enable the use of the SMDK LEDs on the baseboard

Note, this currently only works for S3C64XX based SMDK boards.
config SAMSUNG_PM_CHECK
bool "S3C2410 PM Suspend Memory CRC"
depends on 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 SAMSUNG_PM_CHECK_CHUNKSIZE
int "S3C2410 PM Suspend CRC Chunksize (KiB)"
depends on PM && SAMSUNG_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.
