Pull ARM new SoC family support from Arnd Bergmann: "Two new SoC families are added this time. Sugaya Taichi submitted support for the Milbeaut SoC family from Socionext and explains: "SC2000 is a SoC of the Milbeaut series. equipped with a DSP optimized for computer vision. It also features advanced functionalities such as 360-degree, real-time spherical stitching with multi cameras, image stabilization for without mechanical gimbals, and rolling shutter correction. More detail is below: https://www.socionext.com/en/products/assp/milbeaut/SC2000.html" Interestingly, this one has a history dating back to older chips made by Socionext and previously Matsushita/Panasonic based on their own mn10300 CPU architecture that was removed from the kernel last year. Manivannan Sadhasivam adds support for another SoC family, this is the Bitmain BM1880 chip used in the Sophon Edge TPU developer board. The chip is intended for Deep Learning applications, and comes with dual-core Arm Cortex-A53 to run Linux as well as a RISC-V microcontroller core to control the tensor unit. For the moment, the TPU is not accessible in mainline Linux, so we treat it as a generic Arm SoC.

		Milbeaut SRAM for smp bringup

		Milbeaut SoCs use a part of the sram for the bringup of the secondary cores.
		Once they get powered up in the bootloader, they stay at the specific part
		of the sram.
		Therefore the part needs to be added as the sub-node of mmio-sram.

		Required sub-node properties:
		- compatible : should be "socionext,milbeaut-smp-sram"

		Example:

		sram: sram@0 {
		compatible = "mmio-sram";
		reg = <0x0 0x10000>;
		#address-cells = <1>;
		#size-cells = <1>;
		ranges = <0 0x0 0x10000>;

		smp-sram@f100 {
		compatible = "socionext,milbeaut-smp-sram";
		reg = <0xf100 0x20>;
		};
		};

		Milbeaut SoCs Timer Controller

		Required properties:

		- compatible : should be "socionext,milbeaut-timer".
		- reg : Specifies base physical address and size of the registers.
		- interrupts : The interrupt of the first timer.
		- clocks: phandle to the input clk.

		Example:

		timer {
		compatible = "socionext,milbeaut-timer";
		reg = <0x1e000050 0x20>
		interrupts = <0 91 4>;
		clocks = <&clk 4>;
		};
