From 579cadee96542200b69efa3bda7ec4898c8153f6 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Wed, 4 Sep 2013 11:34:08 +0100 Subject: tile: io: implement dummy relaxed accessor macros for writes write{b,w,l,q}_relaxed are implemented by some architectures in order to permit memory-mapped I/O accesses with weaker barrier semantics than the non-relaxed variants. This patch adds dummy macros for the write accessors to tile, in the same vein as the dummy definitions for the relaxed read accessors.
