Author: stefanct Date: Sun Oct 28 02:50:08 2012 New Revision: 1620 URL: http://flashrom.org/trac/flashrom/changeset/1620
Log: Add support for Winbond W39F010/W39L010/W39L020.
W39F010 is a 128kB parallel 5V flash chip, 16k bootblocks. W39L010 is a 128kB parallel 3.3V flash chip, 8k bootblocks. W39L020 is a 256kB parallel 3.3V flash chip, 64k/16k bootblocks.
The W39F010 code was tested with a satasii programmer. The first write attempt after an erase returned with verify failure, but the second write attempt was succesful: http://paste.flashrom.org/view.php?id=1418
