The only way an option follows its default is if it doesn't have a visible
prompt.  So:

config IRQ_MXS
	def_bool y if MACH_ASM9260 || ARCH_MXS
	select IRQ_DOMAIN
	select STMP_DEVICE

will cause it to always be defined to 'y' if either of those options are
enabled.  Otherwise, if it has a visible prompt, it follows (in order of
precedence) whatever the user specifies, the configuration file, or the
Kconfig specified default, or 'n'.  (Each limited by selects and
dependencies.)

Is there a particular reason why the option is being offered for user
selection?
