This option does not enable any code directly, but will allow you to
select some other chip drivers which are now considered obsolete,
because the generic CONFIG_JEDEC_PROBE code above should now detect
the chips which are supported by these drivers, and allow the generic
CFI-compatible drivers to drive the chips. Say 'N' here unless you have
already tried the CONFIG_JEDEC_PROBE method and reported its failure
to the MTD mailing list at <linux-mtd@lists.infradead.org>
