config S3C_LOWLEVEL_UART_PORT
	int "S3C UART to use for low-level messages"
	depends on ARCH_S3C64XX
	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 SAMSUNG_ATAGS
	def_bool n
	depends on ATAGS
	help
	  This option enables ATAGS based boot support code for
	  Samsung platforms, including static platform devices, legacy
	  clock, timer and interrupt initialization, etc.

	  Platforms that support only DT based boot need not to select
	  this option.

config S3C_GPIO_SPACE
	int "Space between gpio banks"
	default 0
	help
	  Add a number of spare GPIO entries between each bank for debugging
	  purposes. This allows any problems where an counter overflows from
	  one bank to another to be caught, at the expense of using a little
	  more memory.

config S3C_GPIO_TRACK
	bool
	help
	  Internal configuration option to enable the s3c specific gpio
	  chip tracking if the platform requires it.
