All non-x86 Chromebooks that use coreboot also use depthcharge. What
exactly do you mean when you say you can't find it? If you parse bios.bin
with cbfstool print, you should see a "fallback/payload" file... that is
depthcharge. (coreboot always requires the payload to just be called
"payload" in CBFS, regardless of what it actually is.) You can extract it
and run 'strings' on it to confirm.
