| 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. | |
