Author: stefanct Date: Tue Oct 2 00:45:08 2012 New Revision: 1611 URL: http://flashrom.org/trac/flashrom/changeset/1611
Log: Add support for SST's 25WF series of SPI flash chips. This includes SST25WF512, SST25WF010, SST25WF020 and SST25WF040. They require a VCC of 1.65 - 1.95V, which is why i could not test them. The SOIC version of the SST25WF512 is used on an AMD X300-based graphics card i own.
