the system regardless of media presence. Device nodes created
with this driver will return -ENODEV upon access.
-config MTD_OBSOLETE_CHIPS
- bool "Older (theoretically obsoleted now) drivers for non-CFI chips"
- help
- 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_JEDECPROBE 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_JEDECPROBE method and reported its failure
- to the MTD mailing list at <linux-mtd@lists.infradead.org>

-config MTD_AMDSTD
- tristate "AMD compatible flash chip support (non-CFI)"
- depends on MTD_OBSOLETE_CHIPS && BROKEN
- help
- This option enables support for flash chips using AMD-compatible
- commands, including some which are not CFI-compatible and hence
- cannot be used with the CONFIG_MTD_CFI_AMDSTD option.
-
- It also works on AMD compatible chips that do conform to CFI.

-config MTD_SHARP
- tristate "pre-CFI Sharp chip support"
- depends on MTD_OBSOLETE_CHIPS
- help
- This option enables support for flash chips using Sharp-compatible
- commands, including some which are not CFI-compatible and hence
- cannot be used with the CONFIG_MTD_CFI_INTELxxx options.

- tristate "JEDEC device support"
- depends on MTD_OBSOLETE_CHIPS && BROKEN
- help
- Enable older JEDEC flash interface devices for self
- programming flash. It is commonly used in older AMD chips. It is
- only called JEDEC because the JEDEC association
- <http://www.jedec.org/> distributes the identification codes for the
- chips.
