+ Device-tree-compatible SH bootloaders are expected to provide the physical
+ address of the device tree blob in r4. Since legacy bootloaders did not
+ guarantee any particular initial register state, kernels built to
+ inter-operate with old bootloaders must either use a builtin DTB or
+ select a legacy board option (something other than CONFIG_SH_DEVICE_TREE)
+ that does not use device tree. Support for the latter is being phased out
+ in favor of device tree.
