From b8224f48feb9c2967e22993b630ad1c6a835b241 Mon Sep 17 00:00:00 2001 From: Ravi Sarawadi Date: Sun, 10 Apr 2022 23:31:24 -0700 Subject: [PATCH] soc/intel/mtl: Do initial Meteor Lake SoC commit till bootblock Base code is based of Intel Alder Lake SOC code. List of changes: 1. Add required Meteor Lake SoC programming till bootblock 2. Include only required headers into include/soc 3. Include MTL-P related DID, BDF 4. Ref: Processor EDS documents vol1 #621483, vol2 #640858 TEST= Build 'util/abuild/abuild -p none -t google/rex -a -c max'.
