[PATCH 3/8] omap: SRAM: flush the right address after memcpy inomap_sram_push

From: Tony Lindgren
Date: Fri Oct 02 2009 - 18:40:25 EST


From: ye janboe <janboe.ye@xxxxxxxxx>

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.
