    PCI/ACPI: Extend pci_mcfg_lookup() to return ECAM config accessors · 13983eb8
    Tomasz Nowicki authored
    pci_mcfg_lookup() is the external interface to the generic MCFG code.
    Previously it merely looked up the ECAM base address for a given domain and
    bus range.  We want a way to add MCFG quirks, some of which may require
    special config accessors and adjustments to the ECAM address range.
    
    Extend pci_mcfg_lookup() so it can return a pointer to a pci_ecam_ops
    structure and a struct resource for the ECAM address space.  For now, it
    always returns &pci_generic_ecam_ops (the standard accessor) and the
    resource described by the MCFG.
    
    No functional changes intended.
