From 45b5a37836d552db30ab571d8ba67f12d7ba23b1 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 29 Apr 2015 22:25:59 -0600 Subject: x86: Add multi-processor init Most modern x86 CPUs include more than one CPU core. The OS normally requires that these 'Application Processors' (APs) be brought up by the boot loader. Add the required support to U-Boot to init additional APs.
