config PLAT_S3C24XX
	bool
	depends on ARCH_S3C2410
	default y if ARCH_S3C2410
	select NO_IOPORT
	help
	  Base platform code for any Samsung S3C device

if PLAT_S3C24XX

config CPU_S3C244X
	bool
	depends on ARCH_S3C2410 && (CPU_S3C2440 || CPU_S3C2442)
	help
	  Support for S3C2440 and S3C2442 Samsung Mobile CPU based systems.

config PM_SIMTEC
	bool
	help
	  Common power management code for systems that are
	  compatible with the Simtec style of power management

config S3C2410_BOOT_WATCHDOG
	bool "S3C2410 Initialisation watchdog"
	depends on ARCH_S3C2410 && 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 ARCH_S3C2410
	help
	  Say y here to use the watchdog to reset the system if the
	  kernel decompressor detects an error during decompression.

config S3C2410_PM_DEBUG
	bool "S3C2410 PM Suspend debug"
	depends on ARCH_S3C2410 && 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 ARCH_S3C2410 && 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 ARCH_S3C2410 && 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.

	  See <file:Documentation/arm/Samsung-S3C24XX/Suspend.txt>

config S3C2410_LOWLEVEL_UART_PORT
	int "S3C2410 UART to use for low-level messages"
	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.

config S3C2410_DMA
	bool "S3C2410 DMA support"
	depends on ARCH_S3C2410
	help
	  S3C2410 DMA support. This is needed for drivers like sound which
	  use the S3C2410's DMA system to move data to and from the
	  peripheral blocks.

config S3C2410_DMA_DEBUG
	bool "S3C2410 DMA support debug"
	depends on ARCH_S3C2410 && S3C2410_DMA
	help
	  Enable debugging output for the DMA code. This option sends info
	  to the kernel log, at priority KERN_DEBUG.

config MACH_SMDK
	bool
	help
	  Common machine code for SMDK2410 and SMDK2440
