This series (along with several patches submitted separately) adds basic support for the amlogic s4 SoCs (S805X2/S905W2/S905Y4). My tree with all patches on it is at [1].
I developed this for a custom board, but I believe a better candidate for a defconfig would be the publicly-available Khadas VIM1S [2]. Unfortunately, I don't own any VIM1S boards, but I have included a sample defconfig in the last patch. If anyone has a VIM1S, please test that patch. You will need to use AMLogic's FIP [3], as I have not yet gotten around to submitting a PR to LibreELEC's FIP.
