in the Aspeed AST2500/AST2400 SoCs when attached to SPI NOR chips,

and support for the SPI flash memory controller (SPI) for

the host firmware. The implementation only supports SPI NOR.

SPIFI is a specialized controller for connecting serial SPI
|
Flash. Enable this option if you have a device with a SPIFI
|
controller and want to access the Flash as a mtd device.

This enables PCI support for the Intel PCH/PCU SPI controller in
|
master mode. This controller is present in modern Intel hardware
|
and is used to hold BIOS and other persistent settings. Using
|
this driver it is possible to upgrade BIOS directly from Linux.

Say N here unless you know what you are doing. Overwriting the
|
SPI flash may render the system unbootable.

To compile this driver as a module, choose M here: the module

will be called intel-spi-pci.
