Subject: [PATCH v3 2/3] ARM: OMAP2+: L2 cache: git rid of redundant cache replacement policy setting
Date: Tue, 22 Apr 2014 13:58:02 +0530	[thread overview]
Message-ID: <8bcc6d587cd1f320b59806dbdee9018b76c04e4f.1398149526.git.nsekhar@ti.com> (raw)
In-Reply-To: <cover.1398149526.git.nsekhar@ti.com>

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.
