Subject: [PATCH v2 1/2] ARM: cache-l2x0: remove __init annotation from initialization functions
Date: Tue,  6 Sep 2011 13:48:26 +0800	[thread overview]
Message-ID: <1315288107-14689-2-git-send-email-shawn.guo@linaro.org> (raw)
In-Reply-To: <1315288107-14689-1-git-send-email-shawn.guo@linaro.org>

If ARM core gets powered off during suspend, L2 cache controller
has to be reinitialized by resume procedure.

The patch removes __init annotation from a few initialization
functions to make the reinitialization possible.  For example,
platform resume function can call l2x0_of_init() to get L2 cache
back to work.
