Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates from Arnd Bergmann: "This release brings up a new platform based on the old ARM9 core: the Nuvoton NPCM is used as a baseboard management controller, competing with the better known ASpeed AST2xx series. Another important change is the addition of ARMv7-A based chips in mach-stm32. The older parts in this platform are ARMv7-M based microcontrollers, now they are expanding to general-purpose workloads. The other changes are the usual defconfig updates to enable additional drivers, lesser bugfixes. The largest updates as often are the ongoing OMAP cleanups, but we also have a number of changes for the older PXA and davinci platforms this time. For the Renesas shmobile/r-car platform, some new infrastructure is needed to make the watchdog work correctly. Supporting Multiprocessing on Allwinner A80 required a significant amount of new code, but is not doing anything unexpected" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (179 commits) arm: npcm: modify configuration for the NPCM7xx BMC.

+
+There is a generic board board-dt.c in the mach folder which support
+Flattened Device Tree, which means, it works with any compatible board with
+Device Trees.

+Allwinner SRAM for smp bringup:
+------------------------------------------------
+
+Allwinner's A80 SoC uses part of the secure sram for hotplugging of the
+primary core (cpu0). Once the core gets powered up it checks if a magic
+value is set at a specific location. If it is then the BROM will jump
+to the software entry address, instead of executing a standard boot.
+
+Therefore a reserved section sub-node has to be added to the mmio-sram
+declaration.
+
+Note that this is separate from the Allwinner SRAM controller found in
+../../sram/sunxi-sram.txt. This SRAM is secure only and not mappable to
+any device.
+
+Also there are no "secure-only" properties. The implementation should
+check if this SRAM is usable first.
+
+Required sub-node properties:
+- compatible : depending on the SoC this should be one of:
+ "allwinner,sun9i-a80-smp-sram"
+
+The rest of the properties should follow the generic mmio-sram discription
+found in ../../misc/sram.txt
+
+Example:
+
+ sram_b: sram@20000 {
+ /* 256 KiB secure SRAM at 0x20000 */
+ compatible = "mmio-sram";
+ reg = <0x00020000 0x40000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0x00020000 0x40000>;
+
+ smp-sram@1000 {
+ /*
+ * This is checked by BROM to determine if
+ * cpu0 should jump to SMP entry vector
+ */
+ compatible = "allwinner,sun9i-a80-smp-sram";
+ reg = <0x1000 0x8>;
+ };
+ };
