of: make of_add_memory available for other board ...

so when the first stage booloader of firmware provide the dtb
we can use it to probe the memory

also allow to print what we probe

of: speed up unflatten ...

We calculate the full path of the current node using fdt_get_path which
takes a lot of time since libfdt has to iterate over the dtb several times.
Speed this up by creating and using a of_find_child function which does
not have to iterate over the whole tree but only over its direct children.
On an i.MX51 board this speeds up unflatten the tree from 60ms to 3.7ms.

of: rename new_device_node to of_new_node and export it ...

of_new_node now takes the parent node and the name as argument and
creates a new node. This simplifies the caller and also makes the
function useful for others, so export it.

of: add of_delete_property ...

This adds a function to delete a property from the currently loaded
devicetree. Also export new_property as of_new_property.

of: unflatten: allow overlay dtbs ...

This implements overlaying a currently loaded dtb with another dtb.
We used to return -EBUSY when a oftree is currently loaded. Instead
of doing this, check if a node already exists before creating a new
one. Similarly, if a property already exists, just overwrite the
value instead of creating a new property.

of: Add support for converting the unflattened tree back to a dtb ...

We already have support for unflattening the devicetree. This patch
adds support for converting it back to a dtb.

of: rename of_parse_dtb to of_unflatten_dtb ...

The process of unflatten the device tree is known from the kernel,
so rename the function, because that's what it does.

of: of_free fixes ...

- Add missing prototype for of_free()
- When root node is freed set root_node to NULL
- (re)scan aliases after freeing a node. This is necessary because
  the freed node may be an alias or point to an alias

of: Fix invalid path for of_find_node_by_path ...

When of_find_node_by_path is called with a non existing path we
return just some node. return NULL instead.

Merge branch 'for-next/console'

of: Check for NULL pointer in of_find_property ...

The console layer calls of_device_is_stdout_path for a new console. When
we are booting without devicetree then of_chosen is NULL which makes barebox
crash. Check for a NULL pointer in of_find_property to prevent this.
