This implements the older VTF ResetVector code often used on EDK II IA32 & X64 platforms.
This VTF requires build time fixups in order to find the SEC entry point. The BaseTools GenFv tool has code that patches the jump target of the reset vector code to match the entry point of the SEC image in the PEI Firmware Volume. v2: * Rename from OldVtf to FixupVtf * Use EDK II extension of .nasmb rather than .nasmbin Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jordan Justen <jordan.l.jus...@intel.com> --- UefiCpuPkg/ResetVector/FixupVtf/Vtf.inf | 32 +++++++++++++++++ UefiCpuPkg/ResetVector/FixupVtf/Vtf.nasmb | 60 +++++++++++++++++++++++++++++++ 2 files changed, 92 insertions(+) create mode 100644 UefiCpuPkg/ResetVector/FixupVtf/Vtf.inf create mode 100644 UefiCpuPkg/ResetVector/FixupVtf/Vtf.nasmb diff --git a/UefiCpuPkg/ResetVector/FixupVtf/Vtf.inf b/UefiCpuPkg/ResetVector/FixupVtf/Vtf.inf new file mode 100644 index 0000000..2450bf6 --- /dev/null +++ b/UefiCpuPkg/ResetVector/FixupVtf/Vtf.inf @@ -0,0 +1,32 @@ +## @file +# Reset Vector +# +# Copyright (c) 2006 - 2014, Intel Corporation.
