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

Mon Nov 27 23:31:19 CET 2023

Since the last test I rebuilt u-boot without the
"CONFIG_DRAM_CLK=792" in the defconfig and got the wrong DRAM size 
problem (showing 2G instead of 1G). I had to do a power down/up to see this.
Are you planning to add this parameter to your patch?
