config SYS_POWER_LOW_POWER_STATE_SUPPORTED
	# Hidden
	bool
	default n
	help
	This option signifies that the target supports the SYS_POWER_LOW_POWER_STATE
	configuration option.

config SYS_POWER_DEEP_SLEEP_SUPPORTED
	# Hidden
	bool
	default n
	help
	This option signifies that the target supports the SYS_POWER_DEEP_SLEEP
	configuration option.

config BOOTLOADER_CONTEXT_RESTORE_SUPPORTED
	# Hidden
	bool
	default n
	help
	This option signifies that the target has options of bootloaders
	that support context restore upon resume from deep sleep

config SIMPLE_FATAL_ERROR_HANDLER
	prompt "Simple system fatal error handler"
	bool
	default n
	default y if !MULTITHREADING
	help
	Provides an implementation of _SysFatalErrorHandler() that hard hangs
	instead of aborting the faulting thread, and does not print anything,
	for footprint-concerned systems. Only enable this option if you do not
	want debug capabilities in case of system fatal error.

config ARCH
	string
	help
	System architecture string.

config SOC
	string
	help
	SoC name which can be found under arch/<arch>/soc/<soc name>.
	This option holds the directory name used by the build system to locate
	the correct linker and header files for the SoC. This option will go away
	once all SoCs are using family/series structure.

config SOC_SERIES
	string
	help
	SoC series name which can be found under arch/<arch>/soc/<family>/<series>.
	This option holds the directory name used by the build system to locate
	the correct linker and header files.

config SOC_FAMILY
	string
	help
	SoC family name which can be found under arch/<arch>/soc/<family>.
	This option holds the directory name used by the build system to locate
	the correct linker and header files.

config BOARD
	string
	help
	This option holds the name of the board and is used to located the files
	related to the board in the source tree (under boards/).
	The Board is the first location where we search for a linker.ld file,
	if not found we look for the linker file in
	arch/<arch>/soc/<family>/<series>
