From mboxrd@z Thu Jan 1 00:00:00 1970 From: gregory.clement@free-electrons.com (Gregory CLEMENT) Date: Mon, 22 Oct 2012 19:02:42 +0200 Subject: [PATCH 0/5] SMP support for Armada XP Message-ID: <1350925368-24243-1-git-send-email-gregory.clement@free-electrons.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
