Subject: [PATCH 87/97] ARM: l2c: omap2+: get rid of redundant cache replacement policy setting
Date: Mon, 28 Apr 2014 20:33:36 +0100	[thread overview]
Message-ID: <E1WerJ2-0001Zc-HI@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20140428192419.GV26756@n2100.arm.linux.org.uk>

From: Sekhar Nori <nsekhar@ti.com>
To: linux-arm-kernel@lists.ifradead.org

L2 cache initialization for OMAP4 redundantly sets the cache policy to
Round-Robin. This is not needed since thats the PL310 default anyway.

Removing this reduces the number of platform specific aux control
settings.
