From 2d4986c1683ca4a77a93a5ba63e481f7c5862693 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Fri, 22 Oct 2021 22:07:43 +0200 Subject: cpu,soc/x86: always include cpu/x86/mtrr on x86 CPUs/SoCs All x86-based CPUs and SoCs in the coreboot tree end up including the Makefile in cpu/x86/mtrr, so include this directly in the Makefile in cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is selected be default could be added and the new CPU/SoC without MTRR support can override this option that then will be used in the Makefile to guard adding the Makefile from the cpu/x86/mtrr sub-directory. In cpu/intel all models except model 2065X and 206AX are selcted by a socket and rely on the socket's Makefile.inc to add x86/mtrr to the subdirs, so those models don't add x86/mtrr themselves. The Intel Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the subdirs. The Intel Xeon SP SoC directory contains two sub-folders for different versions or generations which both add x86/mtrr to the subdirs in their Makefiles.
