Subject: MIPS: SMP: Remove plat_smp_ops cpus_done method.

Nothing was using the method and there isn't any need for this hook.  This
leaves smp_cpus_done() empty for the moment.

As suggested by Paul Bolle <pebolle@tiscali.nl>.

From: Ganesan Ramalingam <ganesanr@broadcom.com>
Date: Fri, 9 May 2014 16:36:25 +0530
Subject: MIPS: Netlogic: XLP9XX on-chip SATA support

The XLP9XX SoC has an on-chip SATA controller with two ports. Add
ahci-init-xlp2.c to initialize the controller, setup the glue logic
registers, fixup PCI quirks and setup interrupt ack logic.
