From: Hanna Hawa <hannah@marvell.com>

This commit adds the base Device Tree files for the Armada 8KPlus.
The Armada 8KP SoCs include several hardware blocks, and this
commit only adds support for the AP810 block, that contains the CPU
core and basic peripherals.

AP810 is a high-performance die, includes octal core application
processor based ARMv8-A architecture, two standard high speed DDR4
interface, and GIC-600 interrupt controller.
AP810 Built as part of Marvell’s MoChi AP family products.

Armada-8080 (8KPlus family), include an AP810 block that contains
the CPU core and basic peripherals.

This commit creates the following hierarchy:
 * armada-ap810-ap0.dtsi - definitions common to AP810
 	* armada-ap810-ap0-octa-core.dtsi - description of the octa cores
		* armada-8080.dtsi - description of the 8080 SoC
			* armada-8080-db.dts - description of the 8080 board

Notes:
	Changes in v2:
	- remove affininty mask for PPI
	- add missing regions in GIC address space (GICC, GICH, and GICV)

Please drop this Change-Id from mainline submissions, as we don't carry
such tags.

+Marvell Armada 8KPlus Platforms Device Tree Bindings
+----------------------------------------------------
+
+Boards using a SoC of the Marvell Armada 8KP families must carry
+the following root node property:
+
+ - compatible, with one of the following values:
+
+   - "marvell,armada-8080", "marvell,armada-ap810-octa", "marvell,armada-ap810"
+     when the SoC being used is the Armada 8080
+
+Example:
+
+compatible = "marvell,armada-8080-db", "marvell,armada-8080",
+	     "marvell,armada-ap810-octa", "marvell,armada-ap810"
