See http://www.infradead.org/rpr.html Sender: linux-kbuild-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-kbuild@vger.kernel.org X-Virus-Scanned: ClamAV using ClamSMTP There is no good reason to duplicate the RAPIDIO menu in various architectures. Instead provide a selectable HAS_RAPIDIO symbol that indicates native availability of RAPIDIO support and the handle the rest in drivers/pci. This also means we now provide support for PCI(e) to Rapidio bridges for every architecture instead of a limited subset.
