marcel	b53efb78fa	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.	2008-10-25 06:18:12 +00:00
