This is a very important first step! Good news.

I can understand that. Memory initialization is the most complex task
in coreboot, and require many details to be exactly right, including
e.g. the sequence of steps and timing between steps.

My guess is no.


However, since you have the serial port working, you could try to use
SerialICE (see http://serialice.org/ ) to get a better understanding
of the operations done by the factory BIOS. This can help to create
the code needed in coreboot to bring up a board.
