commit 451476c80b5a44308e3e518d69565907a61337df Author: Lee Leahy leroy.p.leahy@intel.com Date: Mon Apr 20 15:08:28 2015 -0700
vendorcode/intel: Add FSP 1.1 header files
The second step in adding support for FSP 1.1 is to add the header files.
Updates may be done manually to these files but only to support FSP 1.1. An FSPx_y tree should be added in the future as FSP binaries migrate to new FSP specifications.
The files are provided in an EDK2 style tree to allow direct comparison with the EDK2 tree.
BRANCH=none BUG=None TEST=Build for Braswell or Skylake boards using FSP 1.1.
