This flash part has status UNTESTED for operations: ERASE
Please email a report to flashrom at flashrom.org if any of the above
operations
work correctly for you with this flash part. Please include the flashrom
output with the additional -V option for all operations you tested (-V, -rV,
-wV, -EV), and mention which mainboard or programmer you tested. Thanks
for your help!
