0003 DeviceTree Booting
0004 ------------------
0005
0006 Device-tree compatible SH bootloaders are expected to provide the physical
0007 address of the device tree blob in r4. Since legacy bootloaders did not
0008 guarantee any particular initial register state, kernels built to
0009 inter-operate with old bootloaders must either use a builtin DTB or
0010 select a legacy board option (something other than CONFIG_SH_DEVICE_TREE)
0011 that does not use device tree. Support for the latter is being phased out
0012 in favor of device tree.
