How was it implemented? I see several building blocks: - nvramtool and the fallback/normal mecanism. - Many hardware also do have watchdogs, but I believe it's disabled by coreboot. - SerialICE: I'm not sure it can work from coreboot, or how to integrate it in the same flash. Patches to add some kind of support for it in coreboot might exist in gerrit. - libhwremote: works with SerialICE, and was made to work with pciutils and superiotool - Coreboot also has gdb support, and even something like gdbwait, but only in ramstage. - Coreboot also has some code to write to some flash chips, in order to store its logs there.
