From 47a80a045d2f21c6e6857a9380538c086b99c876 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Mon, 7 Dec 2020 13:15:23 +0100 Subject: nb/intel/sandybridge: Move steppings to CPU header The steppings correspond to the CPUID bits 3:0, so move them to the CPU scope, and include the CPU header from files using the stepping macros.
