Hi Jay. We do use a self written payload based on a Linux kernel with a userland application which simply do a kexec to the next kernel. With this payload we do boot into a Linux on an eMMC on one of our Elkhart Lake designs. With iPXE I do not have any experience on Elkhart Lake. Werner

Yes, nice job Werner!
Since you've been working on Elkhart Lake, can I inquire if you have booted it to an OS via eMMC and/or iPXE using coreboot? If so, with which payload?
Thanks,
- Jay

Nice job Werner, I'm completely shocked!

It has been a while now that we started the open letter to Intel regarding open-sourcing the PSE firmware. I am now happy to announce that all this effort was not worthless! Intel pushed the PSE firmware sources yesterday to github [1]!
A big "Thank You!" to all the supporters of the initiative out there.
