From a8ebf6d1d6971b90a20f5bd0465e6d520377e33b Mon Sep 17 00:00:00 2001 From: Fenghua Yu Date: Thu, 20 Dec 2012 23:44:25 -0800 Subject: x86/microcode_core_early.c: Define interfaces for early loading ucode Define interfaces load_ucode_bsp() and load_ucode_ap() to load ucode on BSP and AP in early boot time. These are generic interfaces. Internally they call vendor specific implementations.
