Dmitry Torokhov 82f7c5103d sh: make use of for_each_node_by_type()
Instead of open-coding the loop, let's use canned macro.

Also make sure we are not leaking "cpus" node reference.

Rich Felker eb6b6930a7 sh: fix memory corruption of unflattened device tree
unflatten_device_tree() makes use of memblock allocation, and
therefore must be called before paging_init() migrates the memblock
allocation data to the bootmem framework. Otherwise the record of the
allocation for the expanded device tree will be lost, and will
eventually be clobbered when allocated for another use.

Daniel Lezcano ba5d08c0ea clocksource/drivers: Rename clocksource_probe to timer_probe
The function name is now renamed to 'timer_probe' for consistency with
the CLOCKSOURCE_OF_DECLARE => TIMER_OF_DECLARE change.

Kefeng Wang 2b65893235 sh: Remove unnecessary of_platform_populate with default match table
After patch "of/platform: Add common method to populate default bus",
it is possible for arch code to remove unnecessary callers of
of_platform_populate with default match table.

Kefeng Wang bb8e15d604 of: iommu: make of_iommu_init() postcore_initcall_sync
The of_iommu_init() is called multiple times by arch code,
make it postcore_initcall_sync, then we can drop relevant
calls fully.

Note, the IOMMUs should have a chance to perform some basic
initialisation before we start adding masters to them. So
postcore_initcall_sync is good choice, it ensures of_iommu_init()
called before of_platform_populate.

Rich Felker 044b81f872 sh: add SMP method selection to device tree pseudo-board
Allow selection of plat_smp_ops based on the enable-method cpu
property from device tree and provide dummy ops for booting with a
device tree that does not enable SMP.

Rich Felker 7480e0aabd sh: add device tree support and generic board using device tree
Add a new pseudo-board, within the existing SH boards/machine-vectors
framework, which does not represent any actual hardware but instead
requires all hardware to be described by the device tree blob provided
by the boot loader. Changes made are thus non-invasive and do not risk
breaking support for legacy boards.

New hardware, including the open-hardware J2 and associated SoC
devices, will use device free from the outset. Legacy SH boards can
transition to device tree once all their hardware has device tree
bindings, driver support for device tree, and a dts file for the
board.

It is intented that, once all boards are supported in the new
framework, the existing machine-vectors framework should be removed
and the new device tree setup code integrated directly.
