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, and will switch to utilizing a mainline device tree.
I can already see the upstream DT subtree containing DTS for this board as:
./dts/upstream/src/arm64/allwinner/sun50i-h700-anbernic-rg35xx-2024.dts
Are there any major differences that won't allow you to switch to OF_UPSTREAM for this board?
In this case there are no differences between the DT in the kernel repo and what we put in U-Boot. The main reason for me holding back the switch to OF_UPSTREAM for the H616 was indeed the rather slow update cadence, which somewhat slows down upstreaming of new boards like this. Doing this separately gives us a bit more control and freedom to take DT patches early, for instance when they appear in some Linux -rc1, or even before that (linux-next). I explained my position in more detail here: https://lore.kernel.org/u-boot/191A0F66-E2AE-4D1B-ACBE-E411E135BB61@arm.com/
I think Tom partly convinced me that regular updates together with cherry-picking should solve most of those problems, so I will probably do the switch for the next cycle.
Cheers, Andre
