The `am335x-boneblack-uboot.dts` file was decompiled from the device tree blob present on the beaglebone after upgrading to kernel `6.6.15-ti-rt-arm32-r1`. I tried compiling this file directly from the kernel repository, but this resulted in the BeagleBone no longer booting. This could probably be fixed by recompiling all device tree blobs, but I am lazy and this is easier.
