Thanks for incorporating the feedback.
Few more minor comments based on the new patch:
1. The description of "DieIndex" perhaps should be modified to " Index of the
die in the package" to make it more apt.
2. The description of "DieId" perhaps should be modified to " Unique ID
specific to the die and the associated generation" to make it more apt.
Regards,
Sai

Subject: [edk2platforms][PATCH v2 1/1] IntelSiliconPkg: Add IntelDieInfoProtocol
Added IntelDieInfoProtocol header into IntelSiliconPkg tree.
The purpose is to have generic and unified interface for getting information
about dies installed in the system.
It will be implemented by silicon code.
