enc28j60 is already supported. For others PRs are welcome.

Cool. I should looked at the existing support! For RTCs, I know at least one is noted in the documentation. https://wiki.radxa.com/Zero/dev/RTC_module_ds3231. I need to check and see which ones I have. I believe I have DS3121s, and also DS1307. Does anything need to be changed/added to support DS1307?

Are you planning to create a master 'dtbo' file for sensors, similar to the Pi device implementation? Or individual dtbo files for each sensor? I find the i2c-sensor implementation easy to use, since you just pass in the i2c bus, sensor identifier, and i2c address to the dtbo. But if you choose to establish separate dtbo files, that works too. You will always need to allow for the bus, and i2c address even if separate files.

Raspberry Pi's overlay parameters is exclusive to themselves. Normal U-Boot does not support this, so everything has to be its own overlay. We do split overlays into reusable modules if possible, but that's at source level: https://github.com/radxa-pkg/radxa-overlays/blob/main/arch/arm64/boot/dts/rockchip/overlays/rk3399-spi1-waveshare35.dts#L1-L2

Ah... OK, was just an idea, that seemed reasonable to suggest. It is what it is.
