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.
