Of course, good find.
The reference code blob was actually in the CBFS but unfortunately the
code to run it was disabled if no such blob was directly provided to
<http://review.coreboot.org/#/c/11907/4> now actually works on my
Auron_Paine and correctly boots with framebuffer into a payload.
There is one remaining issue, when using GRUB2 as payload and using the
at_keyboard terminal_input, the machine resets. The last debug print I
can see from GRUB2 is from term/at_keyboard.c:367 with current_set=0, so
I suppose the crasher is the write_mode(1) a few lines down.
Is this a GRUB2 issue or Coreboot issue (the at_keyboard is related to
the EC, maybe not properly initialized)?
Thanks for all involved so far!
