tristate "SPI Flash chips (AT26DF, M25P, W25X, ...)"
depends on SPI
help
This enables access to most modern SPI flash chips, used for
program and data storage. Series supported include Atmel AT26DF,
Spansion S25SL, SST 25VF, ST M25P, and Winbond W25X. Other chips
are supported as well. See the driver source for the current list,
or to add other chips.
Note that the original DataFlash chips (AT45 series, not AT26DF),
need an entirely different driver.
Set up your spi devices with the right board-specific platform data,
if you want to specify device partitioning or to use a device which
doesn't support the JEDEC ID instruction.
config MTD_SST25L
tristate "Support SST25L (non JEDEC) SPI Flash chips"
depends on MTD_M25P80
help
This enables access to the non JEDEC SST25L SPI flash chips, used
for program and data storage.
Set up your spi devices with the right board-specific platform data,
if you want to specify device partitioning.
