Current ftpci100 driver host bridge controller driver requires struct pci_bus to be created in order to mask and clear IRQs using standard PCI bus config accessors. This struct pci_bus dependency is fictitious and burdens the driver with unneeded constraints (eg to use separate APIs to create and scan the root bus). Add PCI raw config space accessors to PCIe ftpci100 driver and remove the fictitious struct pci_bus dependency.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
