Subject: [PATCH 3/4] zImage: __armv3_mpu_cache_flush: respect should-be-zero specification
Date: Tue, 26 Jan 2010 22:28:42 +0100 [thread overview]
Message-ID: <1264541323-3454-3-git-send-email-u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <20100126203835.GC17642@pengutronix.de>
Probably the register content for cache operations is "don't care" in
practice, but as r1 is explicitly zeroed, use that one.
