Subject: [PATCH 3/8] omap: SRAM: flush the right address after memcpy in omap_sram_push
Date: Fri, 02 Oct 2009 15:40:16 -0700	[thread overview]
Message-ID: <20091002224016.11962.18728.stgit@localhost> (raw)
In-Reply-To: <20091002223510.11962.21751.stgit@localhost>

From: ye janboe <janboe.ye@gmail.com>

the original flush operation is to flush the function address which is
copied from.
But we do not change the function code and it is not necessary to flush it.
