NT_FW_CONFIG DTB contains platform information passed by Tf-A boot stage.
This information is used for Virtual memory map generation during PEI phase
and passed on to DXE phase as a HOB, where it is used in
ConfigurationManagerDxe.

This patch adds a PEI to parse NT_FW_CONFIG and pass it to other
PEI modules(as PPI) and DXE modules(as HOB).

v4:
     - Fixed code review comments
     - Split the patch into four patches

Can you add git notes for the patches in the future, please? See https://github.com/tianocore/tianocore.github.io/wiki/Laszlo%27s-unkempt-git-guide-for-edk2-contributors-and-maintainers#contrib-30
Also, it would be of great help if you can add a link to the edk2 mailing list discussion that has taken place. I normally do that as it helps the maintainer locate the previous discussion easily.

For now, can you reply to the individual patches with the links to the previous discussion, please?

Regards,

Sami Mujawar
