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.
