[PATCH 0/2] Add initial support for Khadas VIM 5

[Nick Xie]

This series adds initial support for the Khadas VIM 5, a board based
on the Amlogic A311Y3 SoC.

The first patch documents the board compatible. The second adds the
board device tree with UART B enabled, an 8 GiB memory description,
and the ARM Trusted Firmware reserved memory region.

The board has been boot-tested up to initramfs using the serial
console.

[PATCH 2/2] arm64: dts: amlogic-a9-a311y3-khadas-vim-5: add initial device tree

[Nick Xie]

The Khadas VIM 5 uses the Amlogic A311Y3 SoC, based on the Amlogic A9
SoC family, on a board with the same form factor as the
VIM/VIM2/VIM3/VIM4/VIM1S models. The serial debug console works with this
initial device tree.

It features:
 - 8GB LPDDR5
 - 64GB eMMC 5.1 storage
 - 32MB SPI flash
 - 10/100/1000 Base-T Ethernet
 - AP6275P Wireless (802.11 a/b/g/n/ac/ax, BT5.1)
 - HDMI 2.1 output
 - HDMI 2.1 input
 - 1x USB 2.0 + 1x USB 3.0 ports
 - 1x USB-C with USB 3.0/DP/PD
 - 2x LEDs (1x red, 1x white)
 - 3x buttons (power, function, reset)
 - M2 socket with PCIe, USB, ADC & I2C
 - 1x 4 lanes MIPI DSI
 - 1x 4 lanes MIPI CSI
 - 40pin GPIO Header
 - 1x micro SD card slot
