[PATCH 3/3] sunxi: H616: Add OrangePi Zero 3 board support

Stephen Graf stephen.graf at gmail.com

I built u-boot with the additional parameter for usb and it works, I think.  There was one message that might be of concern "
Card did not respond to voltage select! : -110". I am not sure of the details of the boot.cmd. The output below came from
the supplier image on an SD plugged into a USB card reader. The SD slot of the board was empty.

I was able to install u-boot to the SPI flash memory and there is a warning message from that also: "
Loading Environment from SPIFlash... jedec_spi_nor flash at 0: unrecognized JEDEC id bytes: 5e, 40, 18
*** Warning - spi_flash_probe_bus_cs() failed, using default environment"

Thank you for your advice on getting something to boot. None of the Debian installer images were suitable.  Even SID was at 6.1.
I built the latest Linux 6.6.2 and wrestled with the rootfs before I got it running. I built the tested u-boot with this system,
as a test of system stability.
