Intrigued by that, I went looking. First commit of support was 2019, for Linux5.2. Yet, 5 years later, there is not one example (that i could find) of OpenWrt running on these Chips. If the platform/FW/BSP package were any good, I'd expect there to be chat about it in the forums, and/or attempts to port to such devices from SMBStaX (The Microchip BSP Linux dist).
