Hi,
Check coreboot/util/genprof/README which I forgot to mention. There is a script which transforms that into human readable symbols. Just make sure the build directory contains what has been actually used to run it.
Thanks Rudolf
Function tracing ----------------
Enable CONFIG_TRACE in debug menu. Run the compiled image on target. You will get a log with a lot of lines like:
... ~0x001072e8(0x00100099) ~0x00108bc0(0x0010730a) ...
First address is address of function which was just entered, the second address is address of functions which call that.
You can use the log2dress to dress the log again:
... src/arch/x86/lib/c_start.S:85 calls /home/ruik/coreboot/src/boot/selfboot.c:367 /home/ruik/coreboot/src/boot/selfboot.c:370 calls /home/ruik/coreboot/src/devices/device.c:325 ...
Alternatively, you can use genprof to generate a gmon.out file, which can be used by gprof to show the call traces. You will need to install uthash library to compile that.
Great use is:
make ./genprof /tmp/yourlog ; gprof ../../build/coreboot_ram | ./gprof2dot.py -e0 -n0 | dot -Tpng -o output.png
Which generates a PNG with a call graph.

If you deselect "GDB" support in debug menu, maybe the tracing will print out what it is executing. You just need to turn on tracing support in debug menu.
Ok, I have enabled tracing support and after read resources of PCI DOMAIN 0000 following happens:
