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.
