From f13a944ca6d50efa1dc4cca3a31262b677a2a715 Mon Sep 17 00:00:00 2001 From: Wei Yang Date: Tue, 21 May 2019 14:28:35 +0800 Subject: [PATCH] hw/acpi: Consolidate build_mcfg to pci.c Now we have two identical build_mcfg functions. Consolidate them in acpi/pci.c. Signed-off-by: Wei Yang v4: * ACPI_PCI depends on both ACPI and PCI * rebase on latest master, adjust arm Kconfig v3: * adjust changelog based on Igor's suggestion Message-Id: <20190521062836.6541-2-richardw.yang@linux.intel.com> Reviewed-by: Igor Mammedov Reviewed-by: Michael S.
