I'm very interested in the steps the BIOS takes in
order to do the southbridge
resource configuration. Can you point me to the coreboot
files where these
steps are done, specifically I'm interested in the
ICH7-M chipset, the one
present in all my com express modules, and the steps
to initialize the
superio hardware monitor.
