[coreboot] Intel released first documentation on the PSE for Elkhart Lake SoC

[Zeh, Werner]

Dear coreboot community.

As you know we are currently in discussion with Intel to get the PSE and its documentation on the Elkhart Lake SoC publicly available.

Intel have now released some docs in this regard which can be accessed freely (see [1] and [2]). Feel free to use them as your use case requests.

Though it might be not fully complete it is a good starting point to dig into and get a wider understanding of the PSE and its internals.

There are other referenced documents mentioned in these two which are available, too. Just change the referenced doc number in the link and you will get the other docs as well.

Have fun

Werner
