3mdeb Making Progress On AMD Ryzen AM5 Motherboard Port With Coreboot + openSIL

In addition to the 3mdeb firmware consulting firm porting Coreboot with AMD openSIL to an EPYC 9005 "Turin" Gigabyte motherboard, their developers have also been working on a similar Coreboot + openSIL port to an AM5 Ryzen consumer motherboard.

3mdeb is porting openSIL and Coreboot to the MSI PRO B850-P motherboard. It's still a work-in-progress but should be released this year. I've already bought one of these motherboards in anticipation and will have more details soon.

On Friday they shared a status update that they have re-based their downstream Dasharo code from Coreboot 24.12 to Coreboot 25.12 and have been tackling port configuration in Coreboot.

They continue to plan for upstreaming all of their changes for this MSI AM5 motherboard port to upstream Coreboot once it has reached a mature and stable enough state. AMD's Phoenix openSIL code as a reminder is considered proof-of-concept and not intended for production use. It's with next-gen AMD Zen 6 platforms when openSIL will hopefully be ready to shine at scale.

Those wanting to learn more about this MSI PRO B850-P Coreboot/Dasharo porting can do so via the 3mdeb blog.
