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

[Stephen Graf]

Yes I forgot about the zBIT patch. With this patch also included I built 
and retested u-boot loaded from SPI flash.  The two warning/error 
messages disappeared and the flash worked properly and booted from a USB 
device.

There was one message that I did not understand:
"Loading Environment from SPIFlash... SF: Detected zb25vq128 with page 
size 256 Bytes, erase size 4 KiB, total 16 MiB
*** Warning - bad CRC, using default environment"

I tried to follow the u-boot documentation on writing the SPI flash but 
had problems with the write command.  When issued it returned 
immediately. The erase command took about 5 sec to execute. I researched 
use of mtd commands and got a suggestion to use cat instead, which worked.

"root at orangepizero3:~# mtdinfo
