Add a driver for flash memory that implements to the Common Flash
Memory Interface (CFI). The flash memory can be read and written to through /dev/cfi# and an ioctl() exists so processes can read the query information. The driver supports the AMD and Intel command set, though only the AMD command has been tested. Obtained from: Juniper Networks, Inc.
