The Anbernic RG35XX series of devices are based around an Allwinner
H700 SoC with 1GB of RAM, 2 SD cards, and multiple input buttons.

This bootloader has been tested on the Anbernic RG35XX-2024 and
RG35XX-H, but should be suitable for the entire lineup of H700 based
devices.

A future series of updates will add board selection logic to identify
and load the correct device tree automatically.

So diverging from the rest of sunxi, you are switching to OF_UPSTREAM and
bootstd here, just for that board. Please don't do this. Both methods are
board agnostic, and just depend on generic platform code to work.
I have a patch to switch all H616 boards over to OF_UPSTREAM, so this
wouldn't be needed to be done here. If you want to patch the DT, you could
do this in arch/arm/dts as well.
For bootstd Simon had a series to enable that on sunxi, on which I
commented:
https://lore.kernel.org/u-boot/20240807205032.3745680-1-sjg@chromium.org/

So please keep this board in line with the rest of the sunxi boards, and
we will automatically upgrade it to both OF_UPSTREAM and bootstd as soon
as that's ready.

Also the defconfig looks quite elaborate, are those options really all
needed? The idea of defconfig is just to provide a, well, default. On
sunxi we also try to keep that minimal.

Thanks,
Andre
