The m25p80 driver now depends on MTD_SPI_NOR which is disabled in all defconfigs, so this effectively disables the m25p80 driver in all defconfigs. Fix this by selecting MTD_SPI_NOR which is library code without further dependencies. Also let m25p80 depend on SPI because it needs the SPI code and won't link without it.

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.

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.

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.

The driver provides access to G3 DiskOnChip, distributed by

and doesn't give access to any write operations.
