Adds a function to enable the flash interface on w83697xx superio's.
Still needs to be hooked up to the superio detection framework though.

Hello,
I tried out flashrom on a ASUS OPLX-M motherboard, and it didn't find a flash
device. I found some info by googling (that I cannot verify) that the OPLX-M
would be an OEM (or something) version of the ASUS MEL-M; I suppose this
particular board originally came with a Fujitsu/Siemens PC.

Yes (well, I'd have to write up something), but the solution mentioned
by Michael is way easier, so I'll wait until Michael has diagnosed the
GPIO settings from the flashrom run on factory BIOS.
Regards,
Carl-Daniel

Please rename to S_SPI_FREQ (also all other places with 'SCK'). SCK is
often used to name a clock pin, this is unnecessarily confusing here.

Hm, maybe use strtol() later and check for errors, atoi() is not so
good for that.

^^
Missing spaces.

kHz -> Hz
I would highly recommend to use Hz as the unit for setting the frequency
(in the API). The frontend (flashrom) can easily allow freq=1000,
or freq=1khz, or freq=1mhz etc. for user friendlyness, but the API
should maintain max. flexibility IMHO.

Hello all,
The specific board this is for is the Supermicro H8DGT. Attached is
only the specification, which is not guaranteed to be correct. Use with
care.
Also, after using this, you may want to turn off and unplug the computer
for a few minutes to restore the correct operational state.
The AMD SB700/710/750 Register Reference Guide (#43009) was used as a
reference.
Thanks,
Josh
Secret knowledge is cool, but public knowledge is better.
Implement all Dediprog commands found in USB traces, even if their
purpose is not yet known.
Annotate unknown commands with info about the call sequence they are
embedded in and the firmware version of the log.
Add a new shutdown command for firmware 5.x.
