The board is an Advantech PCM-5820, Super I/O is a Winbond W83977AF, but
with a 0x77 revision (and 0x97 chip ID), which I couldn't find
documented in any datasheet so far. I fixed superiotool to detect it,

I created an initial test patch for Erwan which he's gonna try soon,
here it is (for reference). It's incomplete of course, but enough for
a first try.

The board is used in a robot btw, something like this:

This should make for some cool use-case of LinuxBIOS. Erwan, as soon as this
is working on the board/robot can you write up a short wiki article
with status table of what is working, and especially some boot speed
comparison with the proprietary BIOS? That would be very cool!

Photos or videos of the robot booting and doing stuff would be awesome, too :)

Thanks, Uwe.
