 3DeviceTree Booting
 4------------------

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