[PATCH v3 0/3] SEV Page Encryption Bitmap support for OVMF. 

Changelog :

    in the hypervisor page encryption bitmap after setting the 
    PcdSevEsIsEnabled PCD.

 Changes since v1:
 - Mark GHCB_BASE setup during reset-vector as decrypted explicitly in the  
   hypervisor page encryption bitmap.
 - Resending the series with correct shallow threading.

Feedback from Laszlo :

If Tom and Brijesh agree, I'd like to put the new lib explicitly under their reviewership.

Also, I plan to review this series (v4, at this point) only for formalities. I'd like to receive an R-b from Tom or Brijesh [*], and another from Dov or a colleague at IBM, for this series; those together should suffice for merging the library.
