There still seems to be some confusion. As Alberto alluded to this isn't about verifying your identity. What matters is protecting coreboot along with its adopters and contributors (including companies who sell coreboot-based products) from legal threats. That is far more valuable than any bug fixes you might have to offer.

Perhaps you can fork the repository elsewhere and post your patches, but please keep them out of upstream unless you're willing to do what has been deemed necessary to protect the project from the SCOs of the world. This means abiding by the DCO (https://developercertificate.org/) including its use of the pronoun "I".
