From b4302582f309b49a08c770960a37af6fe1f3afb3 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 4 Aug 2015 12:34:02 -0600 Subject: [PATCH] x86: baytrail: Support operation as an EFI payload Disable a few things which interfere with the EFI init. This allows the Minnowboard MAX to boot into EFI, load a U-Boot payload then boot to the U-Boot prompt.
