From 62e8abf7161b6a0dd32752cd7c60237988f8bff7 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 3 Sep 2013 18:56:46 +0100 Subject: [PATCH] cris: io: implement dummy relaxed accessor macros for writes write{b,w,l}_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 Cris, in the same vein as the dummy definitions for the relaxed read accessors.
