From ca5c23c3b8882d61bf19b7685f2244501902869f Mon Sep 17 00:00:00 2001 From: Paulius Zaleckas Date: Wed, 27 Feb 2008 01:42:39 +0200 Subject: [PATCH] [MTD] XIP: Use generic xip_iprefetch() instead of asm volatile (...) Untested, but shouldn't break anything... Makes MTD_XIP arch independent. I guess this is why xip_iprefetch() was made for.
