Hrrm. Nothing looks immediately wrong. Are you running this under
qemu? If so, one can attach gdb to qemu and set breakpoints in the
guest. I've used this in the past with success.
BTW, in previous emails I highlighted some disadvantages with a
tighter integration of seabios and coreboot. Could you elaborate on
the reasons why you think this is the best option?
