[coreboot] How to register on Coreboot Mainboard Vendor

Dear Coreboot team,
Good days. We are an OEM&OEM Firewall mini pc manufacturer in SHENZHEN China. We are developing 2.5G firewall Mini PC hareware(we already finished them). And as Coreboot is very poweful and well knowned in firewall field so we are wonding that if we can become a coreboot registered motherboard vendor so user could use coreboot on our devices. May we know how to achieve its requirements ?

Waitng for your comments and thanks a lot.

Best Regards
He Chen
