1.. SPDX-License-Identifier: GPL-2.0 2 3DeviceTree Booting 4------------------ 5 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.
