[coreboot] Trying to support Attro G5G100-P board

[Christoph Grenz]

Hello,

I'm currently experimenting with an Attro G5G100-P industrial board.

According to the documentation the chipset is an Intel i915GM with 
an Intel 82801FBM southbridge (which flashrom shows as ICH6-M).
Inteltool only shows:
	Northbridge: 8086:2590 (unknown)
	Southbridge: 8086:2641 (unknown)

Is the chipset supported (or could it be supported by modifying existing 
code)?

The main superio is a W83627HG-AW, which is already supported.
The board seems to have a second superio which manages the four RS232 ports.
I couldn't yet identify this chip.
The config mode init sequence is 0x67,0x67 at 0x2e
and the config mode registers 20-26 contain 02 08 03 19 34 01 00.

Does anybody know something about this second superio chip? I couldn't find 
anything about this chip and as I don't know how it may look like, I can't 
even locate it on the board.

Thanks,

Christoph
