Lennert Buytenhek 398e692fd5 [ARM] 4298/1: fix memory barriers for DMA coherent and SMP platforms ... This patch: - Switches mb/rmb/wmb back to being full-blown DMBs on ARM SMP systems, since mb/rmb/wmb are required to order Normal memory accesses as well. - Enables the use of DMB and ISB on XSC3 (which is an ARMv5TE ISA core but conforms to the ARMv6 memory ordering model and supports the various ARMv6 barriers.) - Makes DMA coherent platforms (only ixp23xx at the moment) map mb/rmb/wmb to dmb(), as on DMA coherent platforms, DMA consistent mappings are done as Normal mappings, which are weakly ordered.
