From 8907c55e725087633fde1dc0aa942d871451e6a7 Mon Sep 17 00:00:00 2001 From: Jayachandran C Date: Sat, 21 Dec 2013 16:52:20 +0530 Subject: [PATCH] MIPS: Netlogic: Identify XLP 9XX chip Adds processor ID of XLP 9XX to asm/cpu.h. Update netlogic/xlp-hal/xlp.h to add cpu_is_xlp9xx() and to update cpu_is_xlpii() to support XLP 9XX.
