| bool "SPI Support" |
| help |
| The "Serial Peripheral Interface" is a low level synchronous |
| protocol. Chips that support SPI can have data transfer rates |
| up to several tens of Mbit/sec. Chips are addressed with a |
| controller and a chipselect. Most SPI slaves don't support |
| dynamic device discovery; some are even write-only or read-only. |
| |
| SPI is widely used by microcontrollers to talk with sensors, |
| eeprom and flash memory, codecs and various other controller |
| chips, analog to digital (and d-to-a) converters, and more. |
| MMC and SD cards can be accessed using SPI protocol; and for |
| DataFlash cards used in MMC sockets, SPI must always be used. |
| |
| SPI is one of a family of similar protocols using a four wire |
| interface (select, clock, data in, data out) including Microwire |
| (half duplex), SSP, SSI, and PSP. This driver framework should |
| work with most such devices and controllers. |

| help |
| Enable driver model for SPI. The SPI slave interface |
| (spi_setup_slave(), spi_xfer(), etc.) is then implemented by |
| the SPI uclass. Drivers provide methods to access the SPI |
| buses that they control. The uclass interface is defined in |
| include/spi.h. The existing spi_slave structure is attached |

| operations every time a new region is accessed. |
