Reserved memory for simple frame buffer should be created in a different way:
+ aliases { + display0 = &lcdif; + }; + + reserved-memory { + #address-cells = <1>; + #size-cells = <1>; + ranges; + + display_reserved: framebuffer@86fa2000 { + reg = <0x86fa2000 0x80000>; + no-map; + }; + + };
We add a function to change the loaded dts and inject those information. I have added another patch for meson. Right now I'm testing on tinker-s board.
