pci_epf_test always maps the PCI_ENDPOINT_TEST registers to BAR_0. But if BAR_0 is reserved for some other purpose (like in TI's K2G BAR_0 is mapped to application registers and cannot be used to map any other regions), PCI_ENDPOINT_TEST registers cannot be mapped making pci_epf_test unusable. Add support to use any BAR to map PCI_ENDPOINT_TEST registers. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
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.
