From 0f61de8d9dba4ebfc4ea4b2da7f91adc937b3875 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 17 Dec 2014 15:50:37 +0800 Subject: [PATCH] x86: Convert microcode format to device-tree-only To avoid having two microcode formats, adjust the build system to support obtaining the microcode from the device tree, even in the case where it must be made available before the device tree can be accessed.
