This option signifies that the target supports the SYS_POWER_LOW_POWER_STATE
configuration option.

This option signifies that the target supports the SYS_POWER_DEEP_SLEEP
configuration option.

This option signifies that the target has options of bootloaders
that support context restore upon resume from deep sleep

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.

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>
source "arch/*/Kconfig"
source "boards/Kconfig"
