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. 13
