help
|
|
This enables access to AT45xxx DataFlash chips, using SPI.
|
|
Sometimes DataFlash chips are packaged inside MMC-format
|
|
cards; at this writing, the MMC stack won't handle those.

help
|
|
This adds an extra check when data is written to the flash.
|
|
It may help if you are verifying chip setup (timings etc) on
|
|
your board. There is a rare possibility that even though the
|
|
device thinks the write was successful, a bit could have been
|
|
flipped accidentally due to device wear or something else.

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.

This provides an MTD device driver for the M-Systems DiskOnChip
|
|
G3 devices.
|
|
|
|
The driver provides access to G3 DiskOnChip, distributed by
|
|
M-Systems and now Sandisk. The support is very experimental,
|
|
and doesn't give access to any write operations.
