3 | DeviceTree 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. |
