Merge branch 'milbeaut/newsoc' into arm/newsoc

Sugaya Taichi <sugaya.taichi@socionext.com> explains:

Here is the series of patches the initial support for SC2000(M10V) of
Milbeaut SoCs. "M10V" is the internal name of SC2000, so commonly used in
source code.

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

Specifications for developers are below:
 - Quad-core 32bit Cortex-A7 on ARMv7-A architecture
 - NEON support
 - DSP
 - GPU
 - MAX 3GB DDR3
 - Cortex-M0 for power control
 - NAND Flash Interface
 - SD UHS-I
 - SD UHS-II
 - SDIO
 - USB2.0 HOST / Device
 - USB3.0 HOST / Device
 - PCI express Gen2
 - Ethernet Engine
 - I2C
 - UART
 - SPI
 - PWM

Support is quite minimal for now, since it only includes timer, clock,
pictrl and serial controller drivers, so we can only boot to userspace
through initramfs. Support for the other peripherals  will come eventually.

  ARM: multi_v7_defconfig: add ARCH_MILBEAUT and ARCH_MILBEAUT_M10V
  ARM: configs: Add Milbeaut M10V defconfig
  ARM: dts: milbeaut: Add device tree set for the Milbeaut M10V board
  clocksource/drivers/timer-milbeaut: Introduce timer for Milbeaut SoCs
  dt-bindings: timer: Add Milbeaut M10V timer description
  ARM: milbeaut: Add basic support for Milbeaut m10v SoC
