There doesn't appear to be a LICENSE or COPYING file in the Depthcharge tree.

My understanding is that Depthcharge is licensed GPLv2 (or later).

How would I confirm this with an online source?

 Should this query be posted on Chromium list rather than Coreboot list?


Probably. The files in the depthcharge repository  have licenses at the top of each file. They are GPLv2.
