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).

Since sandbox cannot access real devices, an emulation mechanism is
|
|
|
|
|
provided instead. Drivers can be connected up to the sandbox SPI
|
|
|
|
|
bus (see CONFIG_SANDBOX_SPI) and SPI traffic will be routed to this
|
|
|
|
|
device. Typically the contents of the emulated SPI flash device is
|
|
|
|
|
stored in a file on the host filesystem.

|
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.
