[PATCH 0/5] SMP support for Armada XP

[Gregory CLEMENT]

Hello,

The purpose of this patch set is to add the SMP support for the Armada
XP SoCs. Beside the SMP support itself brought by the last 3 patches,
this patch set also adds the support for the coherency fabric unit and
the power management service unit.

The coherency fabric is responsible for ensuring hardware coherency
between all CPUs and between CPUs and I/O masters. This unit is also
available for Armada 370 and will be used in an incoming patch set
for hardware I/O cache coherency.

The power management service unit is responsible for powering down and
waking up CPUs and other SOC units.

The original code is from Yehuda Yitschak, it was reworked by myself
and reviewed by Yehuda.

This patch set is based on 3.7-rc2 and depends one the framework clock
support (the last version was posted last week:
http://thread.gmane.org/gmane.linux.kernel/1375701). The git branch
called ArmadaXP-SMP-for-3.8 is also available at
https://github.com/MISL-EBU-System-SW/mainline-public.git.

Regards,

Yehuda Yitschak (5):
