+Subject: [PATCH 04/16] Platform/RaspberryPi: Fix framebuffer base translation
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On RPi 5, the firmware already returns a CPU address to the framebuffer.
+We need to mask off the VC bus alias so that it's only subtracted when
+present.
+
+Display now works, with a few caveats:
+- the depth does not update from 16 to 32-bit anymore. It's necessary
+to add "framebuffer_depth=32" in config.txt.
+
+- no resolutions higher than 1080p.
