[Qemu-arm] [PATCH v5 12/24] hw: acpi: Export the MCFG getter


From: Samuel Ortiz
Subject: [Qemu-arm] [PATCH v5 12/24] hw: acpi: Export the MCFG getter
Date: Mon, 5 Nov 2018 02:40:35 +0100

From: Yang Zhong <address@hidden>

The ACPI MCFG getter is not x86 specific and could be called from
anywhere within generic ACPI API, so let's export it.
