it is great to hear that.

I did not see any message on this list regarding your problem. Could you
open a new thread so that people searching the Web know what the current
state is and maybe somebody else reading the list has an idea.

Can you elaborate in what regard please to give us some arguments when
talking about coreboot.

If you have the means to publish your current state as a Git repository
somewhere that would be appreciated I guess.

Additionally I do not know what the best way is to send patches to
support a new board. One huge patch which gets the board going right
away or several small patches like serial port, memory initialization, …
and the last one being adding it to the Konfig system.


Thanks,
