Normally I wouldn't promote what we do in this forum, but since you asked...
SysPro Consulting is a team of low-level software/firmware engineers. Developing coreboot+FSP solutions for Intel-based systems is one of our key areas of expertise, and currently makes up the majority of our business. SysPro is one of the licensed coreboot consulting services listed on the coreboot website. We are also one of Intel's firmware ecosystem partners.
Starting back when Intel first came out with the very first FSP, I spent several years providing consulting services directly to Intel working with Intel's FSP team to help enable coreboot+FSP solutions on customer boards and systems based on various Intel platforms (including Bay Trail and Broadwell-DE, which are still popular platforms today, but are potentially on the chopping block for coreboot, which is why I chimed into this discussion).
Since then, I have worked directly with a number of Intel customers to develop custom coreboot+FSP solutions for their products. During 2018 I have expanded SysPro from being just myself as an independent consultant to become a whole team of consultants, and we are anticipating continued growth in 2019 and beyond. Developing custom BIOS and BIOS alternative (e.g. coreboot+FSP) firmware solutions is anticipated to be a significant part of our business going forward.
We also have an FSP source license from Intel so that we can generate custom FSPs as needed for clients that need certain workarounds, bug fixes, or enhanced functionality.

Although I have participated in a number of reviews of coreboot patches, I/we have not directly upstreamed any patches to coreboot.org. As a pure consulting service, the ports and customizations that we have made to coreboot to support our clients' hardware (including the work done for Intel) is turned over to the client at the end of each project to do with as they please. If they choose to upstream it or not to coreboot.org is really up to them, and if they do, it would get upstreamed by them, not by us, since they then own the code.

I anticipate going forward that we will have a greater presence in the coreboot community exactly for that reason.

I wouldn't call either Bay Trail or Broadwell-DE as "outdated" given that Intel customers are still actively designing and building boards and systems based around both of those SoCs. But, I will admit that the FSPs for both were from when FSPs were still being created to the FSP 1.0 spec, which has since been superseded by the FSP 2.0 spec., and it's highly doubtful that Intel would ever go back and make new FSP 2.0 compliant FSPs for these platforms. This obviously puts a burden on the coreboot source code to continue to support platforms based on the older FSP interface, but I don't think that's a good enough reason to decide that support for such platforms should be removed from the coreboot code base just because they don't fully conform to a set of ideal requirements. Yes, it would sure be nice if every platform conformed, but reality isn't always that simple or pretty.

As I previously said, I anticipate going forward that we will have a greater presence in the coreboot community. What exactly that will look like is still TBD.

If it really comes down to it and coreboot drops support for CPUs and SoCs that we are still actively using/supporting for our clients, then we will have to do just that... just work off a branch from the last release when such platforms were still supported, and cherry pick into our branch the subsequent commits of interest on the master branch. But as long as a particular platform is still actively being used, it would be a shame IMHO to drop support for it.

Seems to be an issue with the version of Outlook I am using. Not sure there's anything I can do about that.

I'll try to remember to do that. This reply is in plain text.
