    Subject[PATCH v4 21/21] PCI: versatile: update PCI config space remap function
    Date
    PCI configuration space should be mapped with a memory region type that
    generates on the CPU host bus non-posted write transations. Update the
    driver to use the devm_ioremap_nopost* interface to make sure the correct
    memory mappings for PCI configuration space are used.
