The "Chameleon" board is an Open Hardware board designed and developed
by YuzukiHD, and mimics the Raspberry Pi A form factor. It sports an
Allwinner H618 SoC, and alongside the usual devboard peripherals features
an eMMC chip and four USB-C ports:
https://github.com/YuzukiHD/YuzukiChameleon
Add support for that board with the usual patch trinity: vendor prefix,
board name binding, board .dts file.
Please have a look!
Cheers,
Andre
