This commit will add a protocol/PPI definition which will provide a generic and
unified way to get information about dies installed in the system(PCH, SoC, CPU).
It will be implemented per generation in silicon packages.
v3 changes:
- added EDKII_ prefix to interface
- removed GUID definitons from .h file
- corrected descriptions
- made PPI/protocol GUIDs unique
v2 changes:
- added interface description
- added die specific GUIDs into .dec file

Added IntelDieInfo 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.

Is there a reason to keep "Signature" field?
Do you expect consumers check the Signature before using? It's not a common practice in EDKII today.
Thanks,

Hi Ray,
Thanks for the feedback. This field has been added since a couple of protocols are still using that, and we thought it is used. If you think that it is not necessary and it is not commonly used, it can be deleted in the next patch.
Regards,
Maciej

Better to remove the signature.

Subject: RE: [edk2platforms][PATCH v3 1/1] IntelSiliconPkg: Add IntelDieInfoProtocol
Hi Ray,
Thanks for the feedback. This field has been added since a couple of protocols are still using that, and we thought it is used. If you think that it is not necessary and it is not commonly used, it can be deleted in the next patch.
Regards,
Maciej

Subject: RE: [edk2platforms][PATCH v3 1/1] IntelSiliconPkg: Add IntelDieInfoProtocol
Is there a reason to keep "Signature" field?
Do you expect consumers check the Signature before using? It's not a common practice in EDKII today.
Thanks,
ray
