CONFIG_SPI_FLASH_AT45

AT45 family flash driver

Type: bool

Help

This driver can handle several instances of AT45 family chips that
are enabled by specifying devicetree nodes with the "compatible"
property set to "atmel,at45" and other required properties like
JEDEC ID, chip capacity, block and page size etc. configured
accordingly.

The driver is only capable of using "power of 2" binary page sizes
in those chips and at initialization configures them to work in
that mode (unless it is already done).

Direct dependencies

SPI && FLASH

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.
