Libreboot has so far been biased towards Intel. This needs to end (the sooner, the better). A nice start:
+
<ul>
<li>
- <b>ASUS KGPE-D16</b>: this is a very modern board. It has support for both Fam10h and Fam15h AMD CPUs. The board is still
- new, and still in production. See
- these coreboot mailing list posts:<br/>
- <a href="http://www.coreboot.org/pipermail/coreboot/2015-April/079773.html">post 1</a> and
- <a href="http://www.coreboot.org/pipermail/coreboot/2015-April/079773.html">post 2</a><br/><br/>
-
- The board is fully functional (blobs not required), and will be an instant addition to libreboot.
- See <a href="https://raptorengineeringinc.com/coreboot/kgpe-d16-status.php">https://raptorengineeringinc.com/coreboot/kgpe-d16-status.php</a><br/><br/>
-
- <a href="http://raptorengineeringinc.com/content/base/main.htm">Raptor Engineering Inc</a> (USA) has ported
- this board to coreboot, and is using the port internally on their computing cluster, for
- the research that they do. This is the same company that ported
- the <a href="hcl/kfsn4-dre.html">ASUS KFSN4-DRE</a> which is supported in libreboot.
- The owner (and the
- person who ported the board to coreboot), Timothy Pearson (tpearson on freenode IRC) has reached out to the community,
- in request for funding. This funding will pay for the many months of work (at least 4-5 months, for over 10000
- lines of code any many patches that will need to be split up) to get the code
- upstreamed into coreboot. This is not as simple as just releasing the code; coreboot has a very strict code
- review process (in place to ensure quality control). The patches will have to be split up, with people's
- concerns and comments addressed over a long period, with patches constantly rebased to keep up with the
- latest coreboot master branch. In order to get this done in a decent enough time frame, Raptor Engineering will need
- to work on a more-or-less full-time basis.:
- </li>
- <li>
- Francis Rowe (lead developer of libreboot) is paying for this privately, and will have it
- ready in libreboot as soon as possible.
- </li>
- <li>
- Although Raptor will be working for many months to get this upstreamed (merged in coreboot's master branch
- in the git repository), libreboot will merge it more or less instantly, probably in the same week that the
- code is released for review. Raptor would also of course be rebasing the patches on a regular basis, as part
- of the review process, so even if it takes longer for the patches to be merged in coreboot, libreboot would have
- support for this board.<br/><br/>
-
- This is a <b>very</b> high-end board, making for a powerful server or workstation (desktop) system
- that should easily be more than powerful enough for almost everyone. Timothy has replaced the AGESA
- source in coreboot with native initialization code for AMD. The work that he has done can easily be
- extended to support more hardware, so getting this code out and upstreamed is very important.<br/><br/>
+ TYAN S8230 is very similar, and could probably be ported based on the KGPE-D16. Same GPU too.

- W83627 (SuperIO) might have a public datasheet.
- Board-specific wiring (PCI interrupts, DIMM voltage selection). etc.
- Board seems to use socketed SOIC-8 SPI flash according to tpearson, based on photos available online - looks like a ZIF socket or something else, a clip retaining the chip.
- </li>
- <li>
- tpearson says: Tyan seems to have done the same thing as Asus did and built a whole lot of custom power control circuitry out of FETs.
- According to him, this will take much effort to reverse engineer.
- </li>
- <li>
- IPMI firmware is non-free but optional (for iKVM feature, remote management like Intel ME). Not sure if add-on module or baked in.
- In either case, it might be removed or otherwise excluded because it's a HUGE backdoor. Unlike Intel ME, this isn't signed so can be
- removed, and also replaced theoretically. Is the protocol standard public? If so, might be easy/feasible to replace with free code.

- - might be possible adapt this.
- - You
- might need to use the vendor tools running from under the proprietary BIOS to wipe the Flash chip holding the IPMI firmware,
- if it's baked in. (on KGPE-D16, it's an <a href="http://www.servethehome.com/wp-content/uploads/2013/03/ASUS-ASMB6-iKVM-Module.png">add-on card</a> so just don't add the add-on card - also SOIC-16 according to tpearson. but not sure what form factor used on S8230 - it better not be bl***y WSON).
- </li>
- <li>
- SAS controller requires firmware, but optional. (same thing on KGPE-D16). Board also has SATA, so it's fine.
- NOTE: SAS firmware is already flashed onto the SAS controller, to a dedicated chip. Not uploaded/handled by coreboot or linux kernel.
- </li>
- <li>
- tpearson says: power control circuits are a potential issue, not a definite one. it all depends on how Tyan decided to wire things up
- if they engineered things properly, it should actually be transparent.
- ASUS did not, and required work to get it going (see the notes document)
