^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) Device-tree compatible SH bootloaders are expected to provide the physical
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) address of the device tree blob in r4. Since legacy bootloaders did not

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) that does not use device tree. Support for the latter is being phased out
