From 058f5fdfd9953e7f856285b72f1c652683d5d19b Mon Sep 17 00:00:00 2001 From: Jesper Nilsson Date: Mon, 21 Jan 2008 15:38:22 +0100 Subject: [PATCH] CRIS: Correct comment in io.h to describe reality of I/O space. The old comment stated that it was "junk needed for the arch-independent code but which we never use in the CRIS port", but this is no longer true. --- include/asm-cris/io.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/include/asm-cris/io.h b/include/asm-cris/io.h index d196dd6b2d..b87ce63f53 100644 --- a/include/asm-cris/io.h +++ b/include/asm-cris/io.h @@ -122,8 +122,8 @@ static inline void writel(unsigned int b, volatile void __iomem *addr) #define memcpy_toio(a,b,c) memcpy((void *)(a),(b),(c)) -/* The following is junk needed for the arch-independent code but which - * we never use in the CRIS port +/* I/O port access.
