REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3907

The purpose of those changes is to introduce the way to enumerate and assign resources in PEI for the systems with more than one PCI root. 
Here is a need to have an interface that will support such a mechanizm.
For now, the part that performs the enumeration will be implemented in the silicon code.
Sample code can be seen here: https://github.com/mczaj/edk2-platforms/commit/d443062e58f9fba228869b54f2546d9735b3b506

Thanks, the series look good to me. I have given my R-B tag for both of the patches.
Will wait some time to see if there are comments from other reviewers. If no further feedback received, I will merge the series before the end of this week.

Best Regards,
Hao Wu
