From 807d3330d4e8131169e2fce02f1d7b81902e16ab Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Fri, 2 Jun 2023 15:42:08 +0530 Subject: [PATCH] soc/intel/meteorlake: Introduce different SoC flavors of Meteor Lake This patch introduces the different SoC flavors of Intel Meteor Lake as: * MTL-U * MTL-P * MTL-S MTL-U and MTL-P are PCH less designs, while MTL-S is with PCH die. The task for mainboard is to specify the correct SoC type rather than selecting the MTL SoC by default. This change is necessary to support the different SoC flavors of Intel Meteor Lake. BUG=b:276697173 TEST=Able to build and boot google/rex.
