Merge tag 'soc-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc into next
Pull part one of ARM SoC updates from Olof Johansson: "A quite large set of SoC updates this cycle. In no particular order: - Multi-cluster power management for Samsung Exynos, adding support for big.LITTLE CPU switching on EXYNOS5 - SMP support for Marvell Armada 375 and 38x - SMP rework on Allwinner A31 - Xilinx Zynq support for SOC_BUS, big endian - Marvell orion5x platform cleanup, modernizing the implementation and moving to DT. - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so that their platform can be enabled in the same kernel binary as most of the other v7 platforms in the tree. \o/ The work isn't quite complete, there's some driver fixes still needed, but the basics now work. New SoC support added: - Freescale i.MX6SX - LSI Axxia AXM55xx SoCs - Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800 - STi STIH407 plus a large set of various smaller updates for different platforms.

+Samsung Exynos SYSRAM for SMP bringup:
+------------------------------------
+
+Samsung SMP-capable Exynos SoCs use part of the SYSRAM for the bringup
+of the secondary cores. Once the core gets powered up it executes the
+code that is residing at some specific location of the SYSRAM.
+
+Therefore reserved section sub-nodes have to be added to the mmio-sram
+declaration. These nodes are of two types depending upon secure or
+non-secure execution environment.
+
+Required sub-node properties:
+- compatible : depending upon boot mode, should be
+ "samsung,exynos4210-sysram" : for Secure SYSRAM
+ "samsung,exynos4210-sysram-ns" : for Non-secure SYSRAM
+
+The rest of the properties should follow the generic mmio-sram discription
+found in ../../misc/sysram.txt
+
+Example:
+
+ sysram@02020000 {
+ compatible = "mmio-sram";
+ reg = <0x02020000 0x54000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0x02020000 0x54000>;
+
+ smp-sysram@0 {
+ compatible = "samsung,exynos4210-sysram";
+ reg = <0x0 0x1000>;
+ };

+ compatible = "samsung,exynos4210-sysram-ns";
+ reg = <0x53000 0x1000>;
