Hi Andre!
Thanks for your patches. I started checking and noticed that USB storage
was not working:
=> usb reset
resetting USB...
Bus usb@5200000: USB EHCI 1.00
Bus usb@5200400: USB OHCI 1.0
scanning bus usb@5200000 for devices... 1 USB Device(s) found
scanning bus usb@5200400 for devices... 1 USB Device(s) found
scanning usb for storage devices... 0 Storage Device(s) found
=> usb storage
No storage devices, perhaps not 'usb start'ed..?
Otherwise my OpiZero3 (4GB) board looks working.
Ethernet works with my 10 Mbps usb-dongle.
sf probe detect spi nor flash:
=> sf probe
SF: Detected zb25vq128 with page size 256 Bytes, erase size 4 KiB, total
16 MiB
Loading the kernel and running the operating system (from microsd) also
without problems.

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.
