Ok. I guess my board enable code doesn't work properly. Maybe you can
help me look into the relevant registers manually?
Please download http://stuge.se/io.c and compile it using:
gcc -O2 -o io io.c
setpci -d 1106:3227 e6.b 88.l
The command should print one hexadecimal byte and one hex long.
Please save these values.
Use bits 8-15 as port bits 8-15 and use 4f as bits 0-7, then please
(Replace __ here with bits 8-15 from the hex long value from setpci.)
After this, please run flashrom with the patch. (It will still fail.)
Then please run the setpci and io command again, and finally send an
email with the output from all commands.
Thanks for your help!
