Will AMD's 'openSIL' Library Enable Open-Source Silicon Initialization With Core...

Formerly known as LinuxBIOS, coreboot is defined by Wikipedia as "a software project aimed at replacing proprietary firmware (BIOS or UEFI) found in most computers with a lightweight firmware."

Phoronix is wondering if there's about to be a big announcement from AMD:

AMD dropped a juicy tid-bit of information to be announced next month with "openSIL" [an open-source AMD x86 silicon initialization library], complete with AMD Coreboot support....

While about a decade ago AMD was big into Coreboot and at the time committed to it for future hardware platforms (2011: AMD To Support Coreboot On All Future CPUs) [and] open-source AGESA at the time did a lot of enabling around it, that work had died off. In more recent years, AMD's Coreboot contributions have largely been limited to select consumer APU/SoC platforms for Google Chromebook use. But issues around closing up the AGESA as well as concerns with the AMD Platform Security Processor (PSP) have diminished open-source firmware hopes in recent years....

For the Open Compute Project Regional Summit in Prague, there is a new entry added with a title of OSF on AMD — Enabled by openSIL (yes, folks, OSF as in "Open-Source Firmware").... [H]opefully this will prove to be a monumental shift for open-source firmware in the HPC server space.
From the talk's description:

openSIL (AMD open-source x86 Silicon Initialization Library) offers the versatility, scalability, and light weight interface to allow for ease of integration with open-source and/or proprietary host boot solutions such as coreboot, UEFI and others and adds major flexibility to the overall platform design.

In other words, this library-based solution simply allows a platform integrator to scale from feature rich solutions such as UEFI to slim, lightweight, and secure solutions such as coreboot.
The description promises the talk will include demonstrations "highlighting system bring-up using openSIL integrated with coreboot and UEFI Host Firmware stacks on AMD's Genoa based platforms."
