From 861c056953dc4354414881a5e1d382297ef4ea53 Mon Sep 17 00:00:00 2001 From: Jayachandran C Date: Sat, 21 Dec 2013 16:52:23 +0530 Subject: MIPS: Netlogic: SYS block updates of XLP9XX Add the SYS block registers for XLP9XX, most of them have changed. The wakeup sequence has been updated to set the coherent mode from the main thread rather than the woken up thread.
