From 494ec0d0933784b4d14cfb40380fb77408a8b7ef Mon Sep 17 00:00:00 2001 From: Miao Yan Date: Sun, 22 May 2016 19:37:21 -0700 Subject: x86: qemu: rename qemu/acpi_table.c Rename qemu/acpi_table.c to qemu/e820.c, because ACPI stuff is moved to qfw core, this file only contains code for installing e820 table.
