The OrangePi Zero 3 is a small development board featuring the Allwinner H618 SoC, shipping with up to 4GB of DRAM, Gigabit Ethernet, a micro-HDMI connector and two USB sockets. The board uses LPDDR4 DRAM and an X-Powers AXP313a PMIC, support for which was recently added to U-Boot.
Add a defconfig file selecting the right drivers and DRAM options. Since the .dts file was synced from the Linux kernel repo already, we just need to add one line to the Makefile to actually build the .dtb.
The DRAM parameters were derived from the values found in the BSP DRAM drivers on the SPI NOR flash.
