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