[PATCH v2 0/3] sunxi: add OrangePi Zero 3 board support

[Stephen Graf]

I have tested a newly built u-boot with the patches you provided and it works well.
It is the same configuration as what I have been testing with for the last few weeks.

I loaded the U-boot to SPI flash and tested with the SD card removed from the system
and put in a USB card reader. The output for that test is below.

For completeness you might want to mention that another difference between the zero2
and zero3 is the emac phy going from Realtek to Motorcomm.

Thank you for fixing my patch attempt. It is the first one I have ever done.
Thank you also for your patience with my fumbling attempts. I have learned a lot
from you in the last two weeks.
