commit 726c592882154f99be18c6862dc85aad2e1f1ad5 Author: Stefan Reinauer stefan.reinauer@coreboot.org Date: Wed Jul 15 10:24:18 2015 -0700
payloads: preliminary depthcharge support
This is the first piece of many to build a Chrome OS firmware image right out of an upstream coreboot source tree. This does not provide you with a booting image, because many more steps are necessary, such as deploying the required stages to the A/B sections, adding the root and recovery key, images, and signing the RW sections.
