Banana Pi BPI-M4 ZERO standard support

[ScoreABSM]

I really like this small board but with new revision firmware choice is a nightmare...

Looking for Debian or Ubuntu with XFCE and support for wifi (usb eth at start if needed ok), bluetooth, HDMI sound, QHD display resolution (2560x1440) 

Main tests results:

- Standard Armbian (V25.2.2 Linux 6.6.75 Ubuntu noble XFCE + overlays=bananapi-m4-sdio-wifi-bt)

   -> wifi OK, bluetooth NO, HDMI sound NO, bad display perf, buggy screen size (display 1920 when choosing 2560) 

- Official BPI (V24.8.2 Linux 5.4.125 Debian XFCE + overlays=i2c0 spi1 uart4

   -> wifi OK, Bluetooth NO, HDMI sound NO, bug in screen size (limited to 1920)

- Other rolling releases, starting from minimal, ...: not better ou worse.

 

Any build you know with better results? Please help.

The GPU node needs to be enabled.

There has been adjustments made to the patching for 6.12.y and above, but I haven't messed with yet. Basically nodes need to be added for sound.

As for  Bluetooth. I haven't figured out yet why it doesn't work on Armbian. In my personal builds it works fine. I believe there is some patching or service preventing it from loading. But I can't be sure.

 

I've put a lot of time already into the DTS to get this working on both REVS. To much time in my opinion. Anyone is welcome to do a PR and add and enable the bits if they like. Otherwise peps are just gonna have to wait till I get around to it again.
