I ran the following commands to test the patch:

./flashrom -p satasii -V
./flashrom -p satasii -Vr sata.dump
ls -lh sata.dump
./flashrom -p satasii -VE
./flashrom -p satasii -Vr zero.dump
hexdump zero.dump
./flashrom -p satasii -Vw sata.dump
./flashrom -p satasii -Vv sata.dump

I attached the log as the file is 100K and I was reluctant to just paste it
in the body.

The log is also available on pastebin.com at http://pastebin.com/kHkynj7s

Please let me know if you would like me to run other tests.
