Merge patch series "This series introduces initial U-Boot support for mach-axiado AX3005 SCM3005 board, a quad-core ARM Cortex-A53 (ARMv8/ARM64) platform."

Siu Ming Tong <smtong@axiado.com> says:

Patch 1 adds the device tree files: an SoC-level DTSI describing
GIC-v3, Cadence/Zynq UART, a fixed reference clock, and spin-table
secondary CPU boot, plus a board-level DTS setting the console to
uart3 at 115200 baud with 2 GB DRAM at 0x80000000.

Patch 2 adds mach-axiado to support Axiado SoC-based boards, Kconfig
plumbing (AXIADO_AX3005 and TARGET_SCM3005), defconfig, board source
with ft_board_setup() and a MAINTAINERS entry.

Tested on SCM3005 EVK hardware
