Subject: [PATCH v3 1/3] ARM: OMAP2+: L2 cache: get rid of init call
Date: Tue, 22 Apr 2014 13:58:01 +0530	[thread overview]
Message-ID: <9e9e4a3cae0b383f35a04aa1c060d4f678471f4d.1398149526.git.nsekhar@ti.com> (raw)
In-Reply-To: <cover.1398149526.git.nsekhar@ti.com>

Get rid of init call to initialize L2 cache.
Instead use the init_early machine hook. This
helps in using the initialization routine across
SoCs without the need of ugly cpu_is_*() checks.
