Subject: [RFC PATCH 0/2] Update reserved memory for simple framebuffer
Date: Wed, 19 Feb 2020 19:43:40 +0100	[thread overview]
Message-ID: <20200219184342.15974-1-michael@amarulasolutions.com> (raw)

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 at 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
