rapidio: add IDT CPS/TSI switches
Extentions to RapidIO switch support: 1. modify switch route operation declarations to allow using single switch-specific file for family of switches that share the same route table operations. 2. add standard route table operations for switches that that support route table manipulation registers as defined in the Rev.1.3 of RapidIO specification. 3. add clear-route-table operation for switches 4. add CPSxx and TSIxxx families of RapidIO switches Signed-off-by: Alexandre Bounine <alexandre.bounine@idt.com> Tested-by: Thomas Moll <thomas.moll@sysgo.com> Cc: Matt Porter <mporter@kernel.crashing.org> Cc: Li Yang <leoli@freescale.com> Cc: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
