    Subject[PATCH v3 00/27] PCI: Add for_each_pci_resource and addon_res support
    Date
    First part is for_each_pci_resource support:
    Now pci device resource iteration is done via "for (i=0...)" open code.
    That make code hard to read esp when only bridge or sriov resources
    are involved.

    We want to replace those open code with for_each_pci_resource() to make
    the code more readable.
    Also will add addon_resource handling, and need to make addon resource
    to be treated as normal PCI resources during iteration, add
    for_each_pci_resource will make that support transition more simple.

    To make for_each_pci_resource more efficient. We will use preset bitmap
    of different type for searching next idx.

    Second parts is addon_res support:
    Now there is some non normal pci resources other than standard,rom,
    sriov, bridges.
    Some could be same as standard reg, but using different position.
    Some could have own way to read/write to them.
    Kernel are using different way to hack those resources like abusing
    pci bridge resource spot on non bridge pci device.

    Add addon_resources list in pci_dev for those non-standard resources.
    With this patch, will treat addon-resource like standard resources with
    special ops.

    At last replace some quirk_io with addon_res.

    could get from
    git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-pci-for-each-res-addon-v3
    on top of v3.9-rc2

    -v3: rebase on of v3.9-rc2

    Thanks
