From 429e257ea3bdd14e2401ee3f92d2846773294273 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sun, 26 Jun 2011 14:08:27 -0400 Subject: [PATCH] Blackfin: dpmc: omit RETE/RETN when hibernating The RETE/RETN registers are only used in emulation(JTAG) and NMI nodes, or as scratch registers, neither of which need to be saved/restored as this code doesn't execute at those core event levels.
