From mboxrd@z Thu Jan 1 00:00:00 1970 From: Cyrille Pitchen Subject: [PATCH v6 01/11] PCI: Regroup all PCI related entries into drivers/pci/Makefile Date: Tue, 30 Jan 2018 21:56:49 +0100 Message-ID: References: Return-path: In-Reply-To: In-Reply-To: References: Sender: linux-pci-owner@vger.kernel.org To: bhelgaas@google.com, kishon@ti.com, lorenzo.pieralisi@arm.com, linux-pci@vger.kernel.org Cc: adouglas@cadence.com, stelford@cadence.com, dgary@cadence.com, kgopi@cadence.com, eandrews@cadence.com, thomas.petazzoni@free-electrons.com, sureshp@cadence.com, nsekhar@ti.com, linux-kernel@vger.kernel.org, robh@kernel.org, devicetree@vger.kernel.org, Cyrille Pitchen List-Id: devicetree@vger.kernel.org Clean up drivers/Makefile by moving the pci/endpoint and pci/dwc entries from drivers/Makefile into drivers/pci/Makefile. Since we don't want to introduce any dependency between CONFIG_PCI and CONFIG_PCI_ENDPOINT, we now always execute drivers/pci/Makefile. Hence all Makefiles in drivers/pci/ were updated accordingly so no file is compiled when CONFIG_PCI is not defined. Also, we add a comment to reinforce that EPC and EPF libraries must be initialized before their users. Hence built-in EPC drivers, such as those of Designware, are linked after the endpoint core libraries. Finally, we add another comment to explain why obj-y has been chosen instead of obj-$(CONFIG_PCIE_DW) to parse the dwc/ sub-folder.
