    MIPS: PCI: Introduce CONFIG_PCI_DRIVERS_LEGACY · c5611df9
    Paul Burton authored
    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.
