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"

+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>;

- - interrupts:		The interrupt to map
- - #address-cells:	Set to <1> if the node includes partitions
- - marvell,system-controller: Set to retrieve the syscon node that handles
-			NAND controller related registers (only required
-			with marvell,armada-8k-nand compatible).
-
-Optional properties:
-
- - dmas:			dma data channel, see dma.txt binding doc
- - marvell,nand-enable-arbiter:	Set to enable the bus arbiter
- - marvell,nand-keep-config:	Set to keep the NAND controller config as set
-				by the bootloader
- - num-cs:			Number of chipselect lines to use
- - nand-on-flash-bbt: 		boolean to enable on flash bbt option if
-				not present false
- - nand-ecc-strength:           number of bits to correct per ECC step
- - nand-ecc-step-size:          number of data bytes covered by a single ECC step
-
-The following ECC strength and step size are currently supported:
-
- - nand-ecc-strength = <1>, nand-ecc-step-size = <512>
- - nand-ecc-strength = <4>, nand-ecc-step-size = <512>
