Subject: [PATCH 5/5] [Nios2]: Fix dma mapping end address
Date: Sun, 15 May 2011 21:34:32 +0200	[thread overview]
Message-ID: <1305488072-1765-6-git-send-email-franck.jullien@gmail.com> (raw)
In-Reply-To: <1305488072-1765-1-git-send-email-franck.jullien@gmail.com>

From: Franck JULLIEN <franck.jullien@gmail.com>

The flush_dcache_range function takes an absolute end address
so we have to add start address to the second parameter.
