From 0adf8d3548c3fe6f577bb0f2a7acd855dced8a83 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 11 Mar 2016 22:07:16 -0700 Subject: x86: Add support for running Intel reference code Intel has invented yet another binary blob which firmware is required to run. This is run after SDRAM is ready. It is linked to load at a particular address, typically 0, but is a relocatable ELF so can be moved if required. Add support for this in the build system. The file should be placed in the board directory, and called refcode.elf.
