[PATCH 6/8] rapidio: consolidate RAPIDIO config entry in drivers/rapidio
From: Christoph Hellwig <hch@lst.de>
Date: 2018-10-17 08:02:34
Also in:
linux-arch, linux-kbuild, linux-pci, linux-scsi, lkml
Subsystem:
linux for powerpc (32-bit and 64-bit), linux for powerpc embedded ppc85xx, mips, rapidio subsystem, the rest, x86 architecture (32-bit and 64-bit) · Maintainers:
Madhavan Srinivasan, Michael Ellerman, Scott Wood, Thomas Bogendoerfer, Matt Porter, Alexandre Bounine, Linus Torvalds, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen
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.
