[coreboot] Try to get Intel Atom based COMe-cXLi2 Kontron board running

[Manuel Huber]

Thanks for your quick reply :)


- EM100 sounds like a good idea;

It seems to me as if I should wait for the POST card. By reading the 
Intel specification of the SCH I got the feeling that issuing a 'beep' 
would be quite easy (well - it took me a day to just understand what 
Intel tried to say - but that's probably my fault...) as there is a 
simple buzzer connected to some transistor on the output pin of the SCH. 
Just configuring the Timer and enabling the output... (clock source 
seems to be the main clock source...) But that would have been too easy, 
I guess...

Toggling some GPIO won't be any easier I suppose...

Unfortunately it has to be an Intel Atom as we try to decrease the boot 
time of our current DataLogger:

I have already been pointed to SageBios, but while project leaders are 
deciding where to go it's my task to at least try to get the old system 
running - to be able to estimate the effort and what we can expect as 
result... I'm pretty sure the Intel Atom board is not the best 
starting-point - but there was some hope to at least get some debug 
message out of the board as the chipset seems to have been supported at 
some point in time...

I'm a little frightened that when I finally get the POST card, it will 
not output anything...
