From 466caec026e38df1a3dda117ac90ccc82b8d3f14 Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Sun, 10 Feb 2013 13:18:42 +0530 Subject: [PATCH] ARM: OMAP4+: Remove un-necessary cacheflush in secondary CPU boot path This was borrowed from ARM versatile code with pen_release mechanism but since OMAP uses hardware register based synchronisation, pen_release stuff was dropped. Unfortunately the cacheflush wasn't dropped along with it.
