Subject: [RFC PATCH v2 2/9] x86: AMD changes for Secure Launch Resource Table header file

From: Ross Philipson <ross.philipson@...cle.com>

Introduce the AMD info table that allows the SLRT to be linked in as a
setup_data entry. This allows the SLRT to be found and in addition all
the DLMR information needed by the SKL (Secure Kernel Loader).
