CONFIG_SPI_INTEL_PCI: Intel PCH/PCU SPI flash PCI driver

General informations

The Linux kernel configuration item CONFIG_SPI_INTEL_PCI has multiple definitions:

Intel PCH/PCU SPI flash PCI driver found in drivers/spi/Kconfig

The configuration item CONFIG_SPI_INTEL_PCI:

Help text

This enables PCI support for the Intel PCH/PCU SPI controller in master mode. This controller is used to hold BIOS and other persistent settings. Controllers present in modern Intel hardware only work in hardware sequencing mode, this means that the controller exposes a subset of operations that makes it safer to use. Using this driver it is possible to upgrade BIOS directly from Linux.

To compile this driver as a module, choose M here: the module will be called spi-intel-pci.
