+From ff40052c103ed67677b9c4a17cdcee62ca8f6aed Mon Sep 17 00:00:00 2001
+From: Fu Wei <fu.wei@linaro.org>
+Date: Tue, 25 Nov 2014 17:12:24 +0800
+Subject: [PATCH 2/3] ACPI: add the hardware reduced mode check function in
+ src/lib/src/fwts_acpi_tables.c.
+
+It is a prerequisite for ignoring a missing FACS table in hardware-reduced mode.
+
+Upstream-status: Accepted [14.12.00]
