From 040c9c13778076403198ce93f43c4aa3a1ed3907 Mon Sep 17 00:00:00 2001
From: Vernon Mauery <vernon.mauery@linux.intel.com>
Date: Sat, 17 Nov 2018 14:17:27 -0800
Subject: [PATCH] Keep interrupts enabled until last second
The U-Boot bootm command disabled interrupts almost first thing. This
would prevent a person hitting the power button on the host immediatly
after AC on because the BMC would fail to respond to the espi interrupts
and the host would power off.
