From a133dba9c32e60279f70353ded29b3181d4fc8fe Mon Sep 17 00:00:00 2001 From: Guillaume Gardet <guillaume.gardet@arm.com> Date: Fri, 18 Sep 2020 15:27:37 +0200 Subject: [PATCH] rpi: Use firmware provided device tree Currently the firmware generates a device tree for us that we could just use to adjust ourselves. We then on boot throw that away and use our own built-in device tree to configure device access. This is bad for a multitude of reasons. For starters, it breaks overlay support in config.txt, confusing users. Much worse however is that we are stuck with individual U-Boot builds per board. The firmware can easily give us the right DT depending on the target board and revision though. So let's use the firmware provided device tree instead. That way U-Boot as well as payloads loaded by it can automatically adapt to variants of RPi hardware.
