|

Enable driver model for SPI flash. This SPI flash interface
|
||
(spi_flash_probe(), spi_flash_write(), etc.) is then
|
||
implemented by the SPI flash uclass. There is one standard
|
||
SPI flash driver which knows how to probe most chips
|
||
supported by U-Boot. The uclass interface is defined in
|
||
include/spi_flash.h, but is currently fully compatible
|
||
with the old interface to avoid confusion and duplication
|
||
during the transition parent. SPI and SPI flash must be
|
||
enabled together (it is not possible to use driver model
|
||
for one and not the other).

default y

help
|
||
Many flash memories support erasing small (4096 B) sectors. Depending
|
||
on the usage this feature may provide performance gain in comparison
|
||
to erasing whole blocks (32/64 KiB).
|
||
Changing a small part of the flash's contents is usually faster with
|
||
small sectors. On the other hand erasing should be faster when using
|
||
64 KiB block instead of 16 × 4 KiB sectors.
|
||
|
||
Please note that some tools/drivers/filesystems may not work with
|
||
4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).

Enable the access for SPI-flash-based AT45xxx DataFlash chips.
|
||
DataFlash is a kind of SPI flash. Most AT45 chips have two buffers
|
||
in each chip, which may be used for double buffered I/O; but this
|
||
driver doesn't (yet) use these for any kind of i/o overlap or prefetching.
|
||
|
||
Sometimes DataFlash is packaged in MMC-format cards, although the
|
||
MMC stack can't (yet?) distinguish between MMC and DataFlash
|
||
protocols during enumeration.
