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
sahil (4):
Silicon/ARM/NeoverseN1Soc: Extract NT_FW_CONFIG address passed by TF-A
Platform/ARM/N1Sdp: Add N1SdpNtFwConfigPei PEI module
Platform/ARM/N1Sdp: Enable N1SdpNtFwConfigPei PEI module for N1Sdp
Silicon/ARM/NeoverseN1Soc: Consume N1SdpNtFwConfigPei supplied data
