From c5611df968047fb0b38156497b4242730ef66108 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 5 Oct 2016 18:18:12 +0100 Subject: MIPS: PCI: Introduce CONFIG_PCI_DRIVERS_LEGACY Introduce 2 Kconfig symbols, CONFIG_PCI_DRIVERS_GENERIC & CONFIG_PCI_DRIVERS_LEGACY, which indicate whether the system should be built to for PCI drivers using the MIPS-specific struct pci_controller API (hereafter "legacy" drivers) or more generic drivers using only functionality provided by the PCI core (hereafter "generic" drivers). The Kconfig entries are created such that platforms have to select CONFIG_PCI_DRIVERS_GENERIC if they wish to use it - that is, the default is CONFIG_PCI_DRIVERS_LEGACY so that existing platforms need no modification. The functions declared in pci.h are rearranged with those provided only by pci-legacy.c being guarded by an #ifdef CONFIG_PCI_DRIVERS_LEGACY to ensure they are only used in configurations where they are implemented.
