[coreboot] VIA CN700 / VT8237R support in V4 broken?

[Christian]

Hey list
I currently working on a Igel Thin Client 3210.
The board is very closer to bcom/winnetp680.
CN700 northbridge
VT8237R southbridge
W83679HF SuperIO
A try with this tree did not work.
I'm not new to coreboot and think that the first debug message should
apear on the serial-console, but nothing happens.

I have compiled nearly all via boards to test the ROMs with qemu.
And get always this message:

nothing more ...
There is no "Coreboot Starting bla, bla" message

Amd or Intel boards break later.

Is it a problem with Qemu and Via C7 CPUs or is their something wrong in
the via tree.

Is anybody working on a cn700 board for now.
There are hints for Rev. 3566 code for the southbridge? Is this
important. Does the current code not working?

Thanks Chris
