Quick Analysis of Anbernic RG556 Introduction: I regularly receive developer and pre-production versions of devices from various hardware manufacturers for the purposes of providing mainline Linux and U-Boot support. It's been a bit of a hobby of mine ever since COVID-19 back in 2020. Since 2022, I've received Anbernic devices and provided mainline Linux support for each of them including the Anbernic models RG503, RG353P, RG353PS, RG353V, RG353VS, RG-ARC-D, RG-ARC-S, and RG-Nano.

I've also received a few devices for which I've struggled for one reason or another to get traction with. Specifically, this is the RG35XX (the older Actions Semi SoC based version) and each of the 5 and 6 series devices, specifically the RG505, RG405M, RG405V, and RG556. The Actions Semi device has a very old kernel with almos...
