developers at Google started upstreaming their patches for their new devices. For example the boards Falco, Peppy, Pit and Slippy are now in the coreboot repository. Big thanks for that.
Slippy is a reference board that can't be bought. Peppy is the Acer C720 Falco is the HP Chromebook 14.
Those 3 are all haswell.
So what are Pit and Bolt? Can those be bought?
Could you please write a summary mail or create Wiki pages, what Chromebooks these refer to and what features they have?
As for features... parallel cpu bring up and parallel SMM relocation. It uses relocatable ramstage, dynamic cbmem, and a few other things that I can't think of off the top of my head.
I guess, all of them use native graphics initialization (Fast User Interface (FUI)).
If you have questions about anything in particular can provide more insight.
I’d be very much interested in timing data and comparison to older systems.

I have more stuff queued up from the baytrail work, but that can be found in our repo. Actually, some of it can be upstreamed now. I generalized the parallel cpu bring up and SMM relocation paths so others can use it as well.
See https://chromium.googlesource.com/chromiumos/third_party/coreboot/+/refs/hea... as the library the following as the usage example (look for 'flight_record'): https://chromium.googlesource.com/chromiumos/third_party/coreboot/+/refs/hea...
What existing/old boards would easily profit from this? Even the i945 based boards (Core 2 Duo CPUs I believe)?
Thanks,
Paul
