+config PSTORE
+ bool "Persistant store support"
+ default n
+ help
+ This option enables generic access to platform level
+ persistent storage via "pstore" filesystem that can
+ be mounted as /dev/pstore. Only useful if you have
+ a platform level driver that registers with pstore to
+ provide the data, so you probably should just go say "Y"
+ (or "M") to a platform specific persistent store driver
+ (e.g. ACPI_APEI on X86) which will select this for you.
+ If you don't have a platform persistent store driver,
+ say N.
