Orange Pi 4 (Rockchip 3399)

I bought 2 of these (via AliExpress) back in August of 2020. They have been sitting in a drawer ever since. I was intrigued by them because they have a 6 core big/little setup (with 2 Cortex 72+ cores and 4 Cortex A53 cores).

The above documents basic features and setup. The next stage for me is actual programming which involves reading the datasheet and the technical reference manual (TRM) and writing bare metal code.
