Message-ID: <1392289475-8902-6-git-send-email-thomas.petazzoni@free-electrons.com> (raw)
In-Reply-To: <1392289475-8902-1-git-send-email-thomas.petazzoni@free-electrons.com>

From: Gregory CLEMENT <gregory.clement@free-electrons.com>

This commit adds the basic support for the Armada 375 SOCs. These SoCs
share most of their IP with the Armada 370/XP SoCs. The main
difference is the use of a Cortex A9 CPU instead of the PJ4B CPU. The
interrupt controller and the L2 cache controller are also different
they are respectively the GIC and the PL310.

The support is introduced in armada-mvebu.c, together with Armada
370/XP, but a separate DT structure is added, because Armada 375 will
need a different set of SMP operations when the SMP support is
introduced.
