Architecture-specific documentation is being moved into Documentation/arch/ as a way of cleaning up the top-level documentation directory and making the docs hierarchy more closely match the source hierarchy. Move Documentation/sh into arch/ and fix all in-tree references.

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.
